Brazilian President Luiz Inácio Lula da Silva expressed shock at the fatalities from a massive police operation targeting Rio drug gangs that left scores dead, while residents and rights advocates accused authorities of summary executions during the country's deadliest law enforcement action to date.

Justice Minister Ricardo Lewandowski said Lula was "horrified" by the death toll from the raids on October 28, AFP reported.

"The president is horrified by the number of fatal incidents and was surprised that an operation of this scale was set up without the knowledge of the federal government," Lewandowski said.

Rio de Janeiro state police reported that at least 119 people perished, comprising 115 "narcoterrorists" and four officers.

However, the state public defender's office placed the toll even higher at 132, representing the deadliest police operation in Rio's history.

The raids, involving approximately 2,500 police officers bolstered by armoured vehicles, helicopters and drones, concentrated in northern Rio's Penha Complex and Alemao Complex neighbourhoods. The operation targeted Comando Vermelho, Rio's most powerful criminal organisation.

"The elevated lethality of the operation was expected but not desired," Victor Santos, head of security for Rio state, said at a news conference.

Police and suspected gang members exchanged heavy gunfire, with authorities accusing suspects of barricading in buses and deploying explosive-laden drones to attack police.

"This is not ordinary crime, but narcoterrorism," Governor Claudio Castro wrote on X.

However, angry residents accused police of killings amounting to a massacre, while mourners gathered in streets where bodies lay lined up.

"The state came to massacre, it wasn't a [police] operation. They came directly to kill, to take lives," one woman in Penha Complex told AFP.

"There are people who have been executed, many of them shot in the back of the head, shot in the back. This cannot be considered public safety," 36-year-old resident and activist Raul Santiago told Al Jazeera.

UN Secretary-General António Guterres conveyed concern over the high death toll. "We remind authorities of their obligations under international human rights law, and urge prompt and effective investigations," Guterres's spokesman Stéphane Dujarric stated on October 29.

Castro insisted those slain were all criminals, claiming clashes largely occurred in wooded areas where civilians were unlikely to be present.

"I don't think anyone would be strolling in the forest on the day of the conflict. The only real victims were the police officers," he said.

According to Colonel Marcelo Menezes, the Special Police Operations Battalion (BOPE) formed a barrier, with officers advancing to the Serra da Misericórdia mountain range and surrounding suspects in woods where another group waited, Folha de S. Paulo reported.

Throughout the afternoon and the evening on October 28 and into the next day’s early hours, residents with motorcycle taxi driver support entered woods to retrieve bodies.

Dozens were transported to a square in Penha, where they were lined up.

Attorney Albino Pereira, representing families, identified clear signs of torture, execution and human rights violations.

"You don't even need to be an expert to see that there are burn marks [on the skin]. The shots were fired with the gun pressed against the skin. A body arrived here without a head. The head arrived inside a bag; it had been decapitated. So, this was an extermination," Pereira said.

Supreme Court Minister Flávio Dino stated the court does not impede police work but cautioned it does not legitimise illegalities.

"All these events, all these tragedies, serve to show that we need to develop a general theory of police action, especially on the political level," Dino said.

"But, at the same time, it is not about legitimising a free-for-all with bodies lying around in the middle of the woods, thrown on the ground, because that is not the rule of law."

The Rio de Janeiro Public Prosecutor's Office dispatched forensic technicians to the Institute of Forensic Medicine to conduct independent examinations.

Rights groups questioned the timing of large-scale police operations ahead of major international events. Next week, Rio hosts the C40 World Mayors Summit and Prince William's Earthshot Prize.

Later in November, Brazil welcomes world leaders for the UN climate summit COP30 in

Persistent organic pollutants (POPs), particularly polychlorinated biphenyls (PCBs), are synthetic chemicals known for their extreme stability, toxicity, and potential for long-range transport. Although their production was banned in the late 1970s, PCBs remain widespread in the global ocean due to their hydrophobic nature and strong affinity for organic matter, which enables them to accumulate and biomagnify within food webs. Even trace levels of dissolved PCBs in seawater correspond to significant burdens in plankton, particulate matter, and higher trophic levels, thereby sustaining ecological and human health risks long after emissions have ceased.

This study demonstrates that the differential accumulation potential of PCB congeners in the intermediate waters of the Sea of Japan arises from the interplay of congener-specific air–sea exchange, bio-particle sorption, and remineralization fluxes within a strongly stratified, semi-enclosed basin. During spring, scavenging by phytoplankton and detritus loads particles with PCBs near the surface. The continuous sinking of these particles through the thermocline and their subsequent remineralization below the shallow mixed layer in summer contribute to the accumulation of PCBs in the intermediate waters. This remineralization flux injects PCBs into the subsurface dissolved pool, creating an intermediate layer concentration maximum that exceeds what winter mixing alone would produce. By depicting the seasonal and spatial patterns for CB28, CB101, CB153, and CB180, and quantifying their accumulation factors and biogeochemical flux budgets, we demonstrate that CB153 is the most prone to intermediate layer enrichment, whereas CB28 is the least, despite its large atmospheric input.

Our findings have three broad implications. First, the pronounced subsurface maxima of dissolved PCBs indicate an elevated exposure potential for mid-water and benthopelagic biota. Because our model does not simulate bioaccumulation or trophic transfer, we recommend targeted subsurface monitoring and future integration with bioaccumulation models to quantify species-level risk. Second, as climate warming intensifies summer stratification, two opposing effects on PCB accumulation can be anticipated. On one hand, a shallower mixed layer will weaken winter mixing, leaving more PCBs trapped below the thermocline and thereby enhancing intermediate-water enrichment over successive years. On the other hand, reduced nutrient upwelling under stronger stratification may suppress phytoplankton growth and particle export, weakening the biological pump and consequently reducing the subsurface delivery of PCBs. Finally, by distilling these processes into a semi-enclosed basin paradigm—characterized by restricted water exchange with the outside, seasonal bloom-driven particle export, and congener-specific remineralization—this work offers a transferable model for understanding pollutant cycling in other enclosed seas and fjords.

Flavanols in cocoa can protect blood vessel function following uninterrupted sitting - study



University of Birmingham





New research from the University of Birmingham shows that eating flavanol-rich foods—like tea, berries, apples, and cocoa—can protect vascular health in men from the harmful effects of prolonged sitting.

Sedentary behaviour is prevalent in modern societies; it is estimated that young adults sit for approximately six hours a day, but sitting for long periods induces declines in vascular function.

Previous studies have shown that a 1% reduction in vascular function, as measured by brachial Flow-mediated dilatation (FMD), which measures the elasticity of the arteries, leads to a 13% increased risk of cardiovascular disease, such as heart disease, strokes, and heart attacks.

The researchers wanted to explore if there was a way that diet, particularly foods that are high in flavanols, could help protect against the risk to our vascular system associated with periods of uninterrupted sitting.

Flavanols are a type of polyphenol compound that occur naturally in some fruits, tea, and nuts, and cocoa beans. They have been shown to have cardiovascular health benefits, such as protecting the vascular system during periods of mental stress.

The research has been published today (29 Oct) in the Journal of Physiology.

Dr Catarina Rendeiro, Assistant Professor in Nutritional Sciences at the University of Birmingham, and leading author, said: “Whether we are sitting at desks, behind the wheel of a car, on a train, or on the sofa reading a book or watching TV, we all spend a lot of time seated. Even though we are not moving our bodies, we are still putting them under stress. Finding ways to mitigate the impact that sitting for uninterrupted periods has on our vascular system could help us cut the risk of developing cardiovascular diseases.”

Deaths of cardiovascular disease are on the rise; the British Heart Foundation reports that deaths of working-aged adults in the UK increased by 18% to 21,975 in 2023, compared to 2019. In addition, recent studies have found that cardiovascular diseases cost the UK an estimated £29 billion.

The researchers tested whether consuming flavanols just before two hours of sitting could preserve blood vessel function in the arms and legs. Forty young healthy men, 20 who had higher levels of fitness and 20 who had a lower level of fitness, consumed either a high-flavanol (695 mg of total flavanols per beverage) or low-flavanol cocoa drink (5.6 mg of total flavanols per beverage), before completing a two-hour sitting trial.

The study was not carried out with women, as changes in oestrogen levels during the menstrual cycle are suspected to affect the impact of flavanols on vascular health during sitting. This should be the focus of another future trial.

The team took a range of vascular measures before and after sitting, including:

  • FMD in the superficial femoral artery and the brachial artery,
  • arterial resting shear rate and blood flow
  • systolic and diastolic blood pressure
  • leg muscle oxygenation

Both the lower and higher fitness groups who had the low-flavanol cocoa before sitting, experienced FMD declines in the arteries in their arms and legs. This suggests that higher levels of fitness do not provide protection from sitting. It also significantly increased diastolic blood pressure, decreased shear rate and blood flow in both arteries, and resulted in declines in muscle oxygenation in both fitness groups.

However, the research found that those groups who consumed the high-flavanol cocoa drink, again in both fitness groups, did not experience FMD declines in either of the arteries in their arms or legs. This is the first time flavanols have been shown to be effective at preventing sitting-induced vascular dysfunction, in young healthy men.

Dr Sam Lucas, Professor of Cerebrovascular, Exercise & Environmental Physiology at the University of Birmingham and co-author of the study, said: “Our experiment indicates that higher fitness levels do not prevent the temporary impairment of vascular function induced by sitting when only drinking low-flavanol cocoa. Importantly, after the high-flavanol drink, both fitter and less-fit participants kept their FMD the same as it was before sitting for two hours.”

The study is also the first to demonstrate that baseline levels of cardiorespiratory fitness do not alter the vascular effects of flavanol intake. This means that individuals can benefit from flavanol intake regardless of their levels of physical fitness.

Alessio Daniele, PhD student from the University of Birmingham, added: “It is actually quite easy to add high flavanol foods to your diet. There are cocoa products available in supermarkets and health stores which are processed through methods that preserve flavanol levels. If cocoa isn’t your thing, fruits like apples, plums and berries, nuts, and black and green tea are all common kitchen staples and are readily available.”

Dr Catarina Rendeiro concluded: “Our research shows that consuming high-flavanol foods and drinks during periods spent sitting down is a good way to reduce some of the impact of inactivity on the vascular system.

“Given how common sedentary lifestyles have become and the increased risk this can have to vascular health, using flavanol-rich food and drink, especially in combination with breaking up periods of inactivity by going for a short walk or standing up, could be a good way to enhance long-term health, no matter the individual’s fitness level.”
