Operation Sindoor: Understanding Context And Consequences – Analysis


By 

By Sameer Patil and Rahul Rawat


On the intervening night of 6-7 May, 2025, from 01:05 to 01:30 AM, Indian armed forces conducted a tri-service military operation codenamed ‘Operation Sindoor’. It targeted terrorist infrastructure in Pakistan and Pakistan-occupied Jammu and Kashmir (PoJK), aiming to neutralise the operational capabilities of groups responsible for cross-border terrorism on Indian soil.

India said the operation was intended to “pre-empt” and “deter” cross-border terrorism, specifically the Pahalgam attack of 22 April, 2025, that killed 26 civilians (25 Indians and one Nepali) at Baisaran Valley in Jammu and Kashmir.

The Indian government attributed the attack to The Resistance Front (TRF), a proxy of the Lashkar-e-Taiba (LeT). The group had initially claimed responsibility for the attack and subsequently denied it, alleging a “cyber intrusion”.

India described its actions as “focused, measured and non-escalatory in nature”. The operation deliberately avoided targeting Pakistani military installations to minimise the risk of escalation. Defence Minister Rajnath Singh claimed that Operation Sindoor was an “ongoing operation”. He also stated that the strikes had killed over 100 terrorists.

Among the most notable casualties was Jaish-e-Mohammed (JeM) leader Abdul Rauf Azhar, who was involved in the IC-814 hijacking of December 1999 and the killing of American journalist Daniel Pearl. Reportedly, 10 family members of JeM chief Masood Azhar were killed.


This was the most expansive military operation conducted by the Indian armed forces since the 1971 War. Moreover, unlike previous operations such as the 2016 surgical strikes and the 2019 Balakot airstrike, which were targeted responses, Operation Sindoor constituted a multi-domain, high-precision offensive spread across Pakistan’s Punjab province and PoJK, signalling a strategic evolution in India’s approach to cross-border terrorism.

The operation involved precision strikes targeting nine sites—four in Pakistan and five in PoJK—linked to anti-India terrorist groups such as the LeT, JeM and the Hizbul Mujahideen. The targeted sites included Muridke (LeT headquarters) and Bahawalpur (JeM headquarters).

Operation Sindoor: The Details

Operation Sindoor was an intelligence-driven operation that leveraged satellite surveillance, drone technology and human intelligence. Indian Air Force (IAF) fighter jets took off under the guise of a training exercise, employing radar blackouts and NOTAM (Notice to Airmen) to mask their movement and maximise surprise. The operation was conducted through stand-off weapons, with missiles being launched by fighter jets from Indian territory. India used two key weapon systems for the operation: SCALP & HAMMER. In addition, India also used SkyStriker suicide drones, which can carry a warhead of up to 10kg.

  • SCALP, also known as Storm Shadow, is an air-launched cruise missile well-known for its stealth feature and primarily employed for long-range deep-strikes into enemy territory.
  • HAMMER (Highly Agile Modular Munition Extended Range) is an all-weather air-to-ground precision-guided munition (PGM) manufactured by France-based Safran. The PGM is insensitive to jamming and can be launched from low altitude over rough terrain.

The choice of precision-guided munitions was meant to neutralise target sites without causing any major collateral damage in the form of civilian casualties.

Aftermath of the Attack: Action-Reaction Cycle of Escalation

Following Operation Sindoor, Pakistan claimed the Indian action as an act of aggression intended to target civilians. It claimed that the Indian action had killed 26 Pakistani civilians and injured 46 others. Islamabad also underlined Article 51 of the United Nations Charter to claim the right to retaliate against India as per “a time and place of its own choosing”.

Pakistan has responded by conducting heavy shelling along the adjacent regions of the LoC, killing at least 12 Indian civilians, one army jawan, and injuring 51. The targets included a gurdwara in Poonch.

In addition, on the intervening night of 7-8 May 2025, Pakistan attempted to engage several military targets in Northern and Western India. These included targets in J&K (Awantipura, Srinagar, Jammu), Punjab (Pathankot, Amritsar, Kapurthala, Jalandhar, Ludhiana, Adampur, Bhatinda, Chandigarh, Nal), Rajasthan (Phalodi, Uttarlai) and Gujarat (Bhuj). India neutralised these attacks by employing the Integrated Counter UAS (Unmanned Aerial Systems) Grid and air defence systems.

In response, on 8 May, India targeted Air Defence Radars and Systems in several Pakistani cities, including Rawalpindi, Lahore and Karachi. Lahore’s air defence system was reportedly neutralised. India is also reported to have employed Israeli Harop drones during these raids. This was followed by a series of Pakistani drone raids targeting multiple locations along the western borders, including in Jammu, Pathankot, and Udhampur. The IAF activated its Integrated Counter UAS Grid and other air defence systems, including the S-400 Triumf, Barak-8 MRSAM (medium range surface-to-air missile) and the indigenous Akash, helping set up an air defence umbrella that helped thwart the attacks.

Global Dimension

Diplomatic Signaling:

India briefed the United States (US), United Kingdom (UK), Saudi Arabia, United Arab Emirates (UAE), and Russia about its military operations and related developments.“India’s actions have been focused and precise. They were measured, responsible and designed to be non-escalatory in nature. No Pakistani civilian, economic or military targets have been hit. Only known terror camps were targeted,” a statement issued by the Indian Embassy in Washington and shared by the MEA read. National Security Advisor (NSA) Ajit Doval also spoke to the acting US NSA and Secretary of State Marco Rubio and briefed him about India’s actions. Doval also drew India’s redlines, saying, “India had no intent to escalate but was well prepared to retaliate resolutely, should Pakistan decide to escalate”.

Media Coverage:

The global media coverage has largely painted India’s actions in a favourable light. The Wall Street Journalstated that the  Operation Sindoor was “in retaliation for a deadly militant attack on tourists in Kashmir, intensifying a confrontation between the nuclear-armed neighbors.” The BBC reported that “the Indian defence ministry said the strikes… were part of a “commitment” to hold those responsible for the 22 April attack which left 25 Indians and one Nepali national dead “accountable.” It said the Pahalgam attack was “the worst attack on civilians in the region in two decades, and sparked widespread anger in India.”

The French Le Monde compared the 7 May strikes with two past episodes of response in the wake of terror attacks in Uri and Pulwama. It noted that this time the response was “much more heightened and the retaliatory strikes much stronger”. Referring to Pakistani PM Shehbaz Sharif’s comments on his country’s “right to respond decisively to this unprovoked Indian attack”, the paper noted that “he does not hold the keys to power.”

Anadolu, Türkiye’s state-run news agency, said “multiple explosions were heard in different parts of Pakistan and Pakistani Kashmir,” following India’s strikes. Alongside the Indian military’s statements, it heavily quoted Lt Gen. Ahmed Sharif Chaudhry, the spokesman of Pakistan’s military, and Prime Minister Sharif.

UAE’s The National reported on the civilian suffering on the Indian side from Pakistan’s shelling fire and mentioned Sheikh Abdullah bin Zayed, UAE Deputy Prime Minister and Minister of Foreign Affairs, calling on India and Pakistan to “exercise restraint, de-escalate tension and avoid further escalation that could threaten regional and international peace.”

The Russian Tass news agency focused its reporting on India’s official remarks and highlighted that the strikes aimed at “targeting the roots of cross-border terror planning”.

As it stands, Operation Sindoor represents an ongoing military campaign. It has unequivocally demonstrated a significant evolution in India’s counter-terrorism strategy. It underscores the fact that India now reserves the right to conduct pre-emptive strikes against terrorist outfits irrespective of the location of their bases.

X blocks jailed Imamoglu’s account in Turkey

X blocks jailed Imamoglu’s account in Turkey
In Turkey an "Account withheld" message appears on X account @ekrem_imamoglu, with the explanation that the move is based on a legal demand. / X, screenshot
By Akin Nazli in Belgrade May 8, 2025

X has blocked access to jailed Istanbul mayor Ekrem Imamoglu’s account (@ekrem_imamoglu) in Turkey, the Directorate of Communications Center for Countering Disinformation (DMM, @dmmiletisim), a unit of the Turkish presidency’s Communications Directorate, said on May 8.

The social network said it took the action in response to an order of an Istanbul court, which issued a ruling on a petition submitted by the Istanbul public prosecutor’s office. It added that it had filed a legal challenge against the order.

In its statement, DMM referred to articles in the local penal code as providing legal reasoning for the block aimed at Imamoglu, President Recep Tayyip Erdogan’s chief political rival, widely viewed as having been targeted with politically-motivated charges.

Imamoglu’s English-language account (@imamoglu_int) is still accessible in Turkey.

Ozgur Ozel, leader of Turkey’s main opposition Republican People’s Party (CHP), of which Imamoglu is a member, was reported by Reuters as telling reporters after meeting Imamoglu in prison that blocking the mayor's X account was the "digital pillar of the coup" mounted to stop Turkey electing the president it wants, namely Imamoglu. He added that Imamoglu's messages from prison would be posted on a different X account.

“Take your diploma and come”

In his latest tweet, Imamoglu called on people to gather in front of Istanbul University at 20:30 local time on May 7.

“Take your diploma and come,” he wrote.

He also shared a copy of the university diploma he received from Istanbul University. On March 18, a day before his detention, the university annulled the diploma citing technical reasons said to disqualify it.

A four-year bachelor’s degree is required by anyone wishing to run as a presidential candidate in Turkey, according to local legislation.

Erdogan has served as president since 2014. However, he has failed to provide a copy of a certified diploma, such as Imamoglu shared on X.

Ekrem Imamoglu’s certified university diploma.

Erdogan studied accounting at a three-year vocational school.

Number of followers rises

After his account was blocked, the number of Imamoglu’s followers on X rose to 9.7mn from 9.5mn.

According to the Freedom of Expression Association’s EngelliWeb (@engelliweb) project, Turkey has blocked millions of websites, social media accounts and web pages, offering news and a wealth of other material, since the 2007 introduction of the country’s "Internet law".

Virtual private network (VPN) services, which allow access to blocked web content, are widely used in Turkey.

 

Durham University scientists solve 500-million-year fossil mystery





Durham University





-With images-

A peculiar spiny fossil, once thought to represent one of the earliest molluscs, has now been conclusively reclassified by scientists from Durham University and Yunnan University as something entirely different – a distant relative of sponge-like creatures known as chancelloriids.

This striking revelation is set to reshape our understanding of early animal evolution.

The fossil, named Shishania aculeata, hails from 500-million-year-old Cambrian deposits in Yunnan Province, southern China, a region world-renowned for its remarkably preserved snapshots of ancient life.

Initially interpreted as a primitive mollusc, potentially an ancestor of modern snails, slugs, and clams, Shishania was believed to display mollusc-like features including a muscular foot and specialised mineralised spines.

However, a new international study led by Durham University and published in Science paints a dramatically different picture.

The researchers said the new fossils show that Shishania doesn’t fit with molluscs at all, instead it closely resembles a group of ancient creatures called chancelloriids (bag-like animals covered in defensive spines, anchored to the Cambrian sea floor).

The researchers, using better-preserved specimens and advanced imaging techniques, discovered that many of the features previously thought to indicate molluscan affinity were in fact misleading artefacts of fossilisation.

For example, structures taken to be a ‘foot’ were revealed to be the result of distortion during the fossil’s preservation, a process described as a ‘taphonomic illusion’.

Study co-author, Dr Martin Smith of Durham University said: "These ancient fossils turned out to be masters of disguise. Shishania seemed to show all the hallmarks we might expect of an early mollusc ancestor.

“But as it dawned on us that the mollusc-like outlines of the fossil material represented a work of fossil origami, we were led to re-examine each other part of the interpretation in turn.

“The mystery started to unfurl once we found chancelloriids preserved in a very similar way in the same rock unit."

The reclassification is particularly significant because chancelloriids are an enigmatic group known only from Cambrian rocks, disappearing around 490 million years ago.

Though superficially resembling sponges, their bodies are adorned with star-shaped spicules whose intricate microstructure hints at possible connections to more complex animals.

With its extremely simple spines, Shishania suggests that chancelloriids developed their ornate spicules from scratch, rather than adapting them from pre-existing skeletal structures.

That tells something profound about how complex body plans evolved during the Cambrian explosion – the evolutionary burst that gave rise to all modern animal groups.

Dr Smith admitted the fossils initially seemed to confirm his own long-standing theories about early mollusc ancestors: “When Shishania was first described last year, I was thrilled – it seemed to match the early ‘slug-like’ animals I’d always imagined. But our Chinese colleagues’ new material forced me to re-evaluate everything.”

Further analysis revealed patterns once thought to reflect molluscan biology such as a ‘paintbrush-like’ arrangement in the spines were actually preservation artefacts, as the same patterning occurred randomly across the fossil.

Compression and deformation during fossilisation had also made the simple cylindrical animals appear more anatomically complex than they truly were.

This reinterpretation has implications not only for understanding chancelloriids, but also for identifying other ambiguous Cambrian fossils.

It reopens questions about early mollusc evolution and cautions against over-interpreting ambiguous fossil features.

At the same time, it helps solidify our picture of chancelloriid origins and gives us fresh insight into how evolutionary novelty emerged.

The study underscores the crucial role of China’s fossil-rich strata and exemplifies how international collaboration continues to transform our understanding of life’s earliest chapters.

An international team of primate researchers has published the 25 most endangered primate species in Asia, Africa, Madagascar and South America for the years 2023 to 2025. The publication, supported by the German Primate Center (DPZ) - Leibniz Institute for Primate Research in Göttingen, emphasizes how urgently global conservation measures need to be implemented now to save irreplaceable biodiversity.

"The situation is dramatic. If we don't act now, we will lose some of these species forever," warns Christian Roos, geneticist at the German Primate Center. “But there is hope - if science, politics and society take action together.” The report, compiled by leading primatologists and conservationists, underlines the urgent need for targeted conservation efforts to prevent the final extinction of these species.

The most important findings of the report

A group of experts comprising members of the conservation organizations International Union for Conservation of Nature (IUCN) and Conservation International (CI) as well as the International Primatological Society (IPS) has compiled a list of the 25 most endangered primate species in the world. Habitat destruction, hunting, climate change and illegal wildlife trade are the biggest threats to the animals.

The most endangered species include the Tapanuli orangutan (Pongo tapanuliensis) on Sumatra, with only around 800 individuals left. This makes it the most endangered ape species of all. It was only discovered in 2017 by DPZ scientists, among others. Its skull shape, dentition and genes are different from those of other orangutan species. This was revealed by extensive morphological and genetic analyses of orangutans, in which Christian Roos was also involved.

Many lemurs in Madagascar are also threatened with extinction, including Madame Berthe's mouse lemur (Microcebus berthae). The smallest primate in the world, weighing just 30 grams, was discovered in 1993 by DPZ scientists near the field station in the Forêt de Kirindy. Its population has declined significantly in the last three years. "This species has also disappeared from most of the remaining intact forests, which points to frightening consequences for possible conservation measures. This could be the first primate we lose forever in the 21st century, as there are no captive populations either," says Peter Kappeler, head of the field station in the Forêt de Kirindy.

Measures to protect primates

The report calls urgently for the expansion of crucial area protection measures and the consistent enforcement of these measures in order to permanently preserve critical habitats. At the same time, the report emphasizes the importance of actively engaging indigenous and local communities and empowering them as stewards of their own regions. It also calls for comprehensive policy reform, in particular by tightening laws against illegal wildlife trade and ongoing deforestation. Finally, the report underlines the urgency of mobilizing sufficient financial resources to successfully implement long-term conservation programs. “Every primate species that we lose not only means an irreparable loss for nature, but also for us humans,” says Roos. “Because primates are not only fascinating animals - they are also key species of our ecosystems.” If a key species ceases to exist, no other species is able to occupy its ecological niche and the corresponding ecosystem changes radically.

The 25 most endangered primates in the world

Every two years, the 25 most endangered primate species in the world are announced at the meeting of the International Primatological Society in order to raise public awareness of the critical situation of primates. By listing the endangered primates, the researchers want to draw global attention to the fate of our closest relatives and raise funds for research and conservation measures. The report is based on the expertise of over 100 scientists worldwide.

 

Renowned ecologist Diana Wall Gives back to the ecological community with a posthumous major donation to the Ecological Society of America



Ecological Society of America




The Society is honored to announce a generous bequest from the late Dr. Diana Harrison Wall’s estate. She was a former Ecological Society of America (ESA) president (1999–2000) and an internationally respected figure in soil biodiversity and ecology. Wall, who passed away in March 2024, left a lasting legacy with a donation of $514,000 to ESA, making it one of the largest individual gifts in the Society's history.

Wall's exceptional contributions to ecological science spanned over five decades, during which she made groundbreaking discoveries in soil ecology, particularly in her studies of nematodes and soil biodiversity. A pioneer in her field, Wall’s work in Antarctica and her studies of soil nematodes were instrumental in advancing global understanding of soil ecosystems. As a scientist and leader, she emphasized the interconnectedness of environmental systems and the crucial role that soil organisms play in sustaining ecosystems.

“This extraordinary gift reflects Diana Wall’s deep dedication to the Ecological Society of America and to advancing the practice and application of ecological research,” said current ESA President Stephanie Hampton. “Diana was not only a brilliant scientist but also a passionate advocate for ecology as a critical tool for addressing global environmental challenges. On top of that, she was a role model and mentor to many, who can all attest to her infectious enthusiasm for science. This gift will help ensure that her contributions will continue to inspire future generations of ecologists and decision-makers.”

Wall's bequest will support ESA’s ongoing programs that further its mission of advancing the science and practice of ecology and supporting ecologists throughout their careers.

ESA Executive Director Catherine O'Riordan remarked, “We are deeply grateful for this major gift. Diana’s love for ESA was matched only by her dedication to science and to blazing a trail for others. This generous donation will allow us to expand our efforts to provide the next generation of ecologists with the tools, resources and opportunities they need to succeed.”

Throughout her career, Wall was a driving force behind many significant advances in soil biodiversity research. Her work in the McMurdo Dry Valleys of Antarctica demonstrated the vital role of nematodes in soil ecosystems and how they drive carbon cycling in extreme environments. Wall's fieldwork also uncovered the resilience of soil biota under climate change, making her a leader in the study of ecosystem functioning in both polar and desert ecosystems. She was instrumental in establishing the Global Soil Biodiversity Initiative, which produced the first comprehensive scientific assessment of global soil biodiversity. Wall’s contributions have profoundly shaped our understanding of soil ecology, ecosystem services and the impact of human activity on soil health.

In addition to her scientific endeavors, Wall was an advocate for women and minorities in science, and she contributed her tremendous leadership skills to many entities beyond ESA. Among her many leadership roles, she served as president of the Society of Nematologists, the American Institute of Biological Sciences and the Association of Ecosystem Research Centers. Wall’s numerous accolades include being named a fellow of the American Association for the Advancement of Science, election to membership in the American Academy of Arts and Sciences and the U.S. National Academy of Sciences and receiving the British Ecological Society's President's Medal. Her status as a major figure in Antarctic research is reflected in the USGS and ICSU Scientific Committee on Antarctic Research decision to name an Antarctic valley in her honor — Wall Valley.

Wall’s gift to ESA will ensure that her impact on the field of ecology continues for many years to come. It is a testament to her life’s work and her unwavering belief in the importance of ecological science.

Health care workers, firefighters have increased PFAS levels, study finds



Researchers looked at PFAS serum concentrations in health care workers for the first time and were surprised by what they found




University of Arizona Health Sciences





A study including researchers from the University of Arizona Health Sciences and published in the Journal of Exposure Science & Environmental Epidemiology found that firefighters had higher concentrations of certain per- and polyfluoroalkyl substances, or PFAS, and health care workers had moderate elevations of PFAS in their blood with significantly higher odds of two specific PFAS when compared with other essential workers.

“Our study reinforces previous research showing elevated PFAS levels among firefighters and suggests that health care workers may have unique sources of PFAS exposure as well,” said senior author Kate Ellingson, PhD, an associate professor at the Mel and Enid Zuckerman College of Public Health. “Our findings underscore the need to understand occupational exposure pathways for PFAS among different types of workers.”

PFAS are a class of synthetic chemicals used in a wide range of products because of their stain-, water- and flame-resistant properties. PFAS do not degrade easily over time and are highly stable in the environment, making them capable of contaminating our food, water and material products.

The study sought to assess the differences in blood concentrations of PFAS among a range of frontline workers in Arizona. It is the first to evaluate PFAS levels in individuals working in health care.

Among health care workers, researchers found moderate elevations of certain PFAS (PFHpS and PFUnA), along with notably higher odds of detecting Sb-PFOA and PFDoA compared with individuals in other professions.

Firefighters had the highest concentrations of PFAS in their blood samples, specifically concentrations of PFHxS, Sm-PFOS, n-PFOS and PFHpS. This aligns with previous studies and implies distinct sources of occupational PFAS exposure remain for firefighters in Arizona.

PFAS serum levels in other essential workers declined 6% to 17% per year over the three-year study period; however, there were still notable levels of PFAS in their blood samples.

PFAS data were available for 1,960 study participants, including 280 firefighters and 787 health care workers and 734 other essential workers. 

“Almost all adults in the U.S. have detectable levels of certain PFAS, and people in occupations with more frequent exposure to PFAS-containing materials have been shown to exhibit higher serum concentrations of some PFAS,” said co-author Jeff Burgess, MD, MPH, a professor, the director of the Center for Firefighter Health Collaborative Research at the Zuckerman College of Public Health and a BIO5 Institute member. “Research into occupational exposure to PFAS is vital to reduce the health risks associated with PFAS, including but not limited to increases in rates of certain cancers, increases in cholesterol levels, lower antibody response to certain immunizations, and increased rates of certain adverse reproductive outcomes.”

Firefighters are one of the more widely studied populations because of their frequent contact with sources of PFAS, including the protective gear worn while fighting fires and the foam used to extinguish fires. Other frontline workers, such as health care workers, are not as widely studied.

“To date, PFAS exposure in health care settings has not been widely studied, and the potential sources of exposure remain unclear,” Ellingson said, noting that single-use surgical masks, surgical gowns and X-ray film could be potential sources of PFAS exposure. “Therefore, it’s important to further examine specific exposure routes and health consequences for firefighters and health care workers.”

The study used data collected from July 2020 through April 2023 through the Arizona Healthcare, Emergency Response, and Other Essential Worker Surveillance Study, or AZ HEROES, at the U of A Health Sciences.

In addition to Ellingson and Burgess, co-authors from the University of Arizona Health Sciences include graduate student James Hollister, research manager Shawn Beitel, former graduate student Ferris Ramadan, Karen Lutrick, PhD, associate professor of family and community medicine at the College of Medicine – Tucson, and Julia Fisher, PhD, assistant research professor at the BIO5 Institute. Others who contributed to the research include first author Cedar Mitchell, PhD, an epidemiology field officer for the Centers for Disease Control and Prevention who previously served as an epidemic intelligence service officer with the Pima County Health Department, and Shawn O’Leary and Zhihua Tina Fan, PhD, both of the New Jersey Department of Health.
