Three West African juntas have turned to Russia. The US has declared a stark policy shift towards three West African countries which are battling Islamist insurgents and whose military governments have broken defence ties with France and turned towards Russia. The state department announced that Nick Checker, head of its Bureau of African Affairs, would visit Mali's capital Bamako to convey the United States' respect for Mali's sovereignty and chart a new course in relations, moving past policy missteps. It adds that the US also looks forward to co-operating with Mali's allies, neighbouring Burkina Faso and Niger, on shared security and economic interests. Absent from the agenda is the longstanding American concern for democracy and human rights.

Breakthroughs, discoveries, and DIY tips sent every weekday. To combat the deadly diseases spread by mosquitoes, entomologists often turn to the blood-sucking insect's reproductive life. Deactivating their sperm, using a mosquito kill bucket to take out mosquito larvae, and now researchers are creating something akin to a sexually-transmitted disease just for mosquitoes. In a study published earlier this year in the journal Scientific Reports, a team of scientists from the United States and Burkina Faso in West Africa, detailed how they delivered a deadly fungal infection to female mosquitoes. The females are the ones who bite and spread disease to humans.

The use of drones by several African countries in their fight against armed groups is causing significant harm to civilians, according to a new report. More than 943 civilians have been killed in at least 50 incidents across six African countries from November 2021 to November 2024, according to the report by Drone Wars UK. The report, titled Death on Delivery, reveals that strikes regularly fail to distinguish between civilians and combatants in their operations. Experts told Al Jazeera that the death toll is likely only the tip of the iceberg because many countries run secretive drone campaigns. As drones rapidly become the weapon of choice for governments across the continent, what are the consequences for civilians in conflict zones?

Combining large language models during training or at inference time has shown substantial performance gain over component LLMs. This paper presents LLM-TOPLA, a diversity-optimized LLM ensemble method with three unique properties: (i) We introduce the focal diversity metric to capture the diversity-performance correlation among component LLMs of an ensemble. (ii) We develop a diversity-optimized ensemble pruning algorithm to select the top-k sub-ensembles from a pool of $N$ base LLMs. Our pruning method recommends top-performing LLM subensembles of size $S$, often much smaller than $N$. (iii) We generate new output for each prompt query by utilizing a learn-to-ensemble approach, which learns to detect and resolve the output inconsistency among all component LLMs of an ensemble. Extensive evaluation on four different benchmarks shows good performance gain over the best LLM ensemble methods: (i) In constrained solution set problems, LLM-TOPLA outperforms the best-performing ensemble (Mixtral) by 2.2\% in accuracy on MMLU and the best-performing LLM ensemble (MoreAgent) on GSM8k by 2.1\%. (ii) In generative tasks, LLM-TOPLA outperforms the top-2 performers (Llama70b/Mixtral) on SearchQA by $3.9\mathrm{x}$ in F1, and on XSum by more than $38$ in ROUGE-1. Our code and dataset, which contains outputs of 8 modern LLMs on 4 benchmarks is available at https://github.com/git-disl/llm-topla

Following 11 years of defence cooperation and millions of dollars spent on maintaining military bases, the United States officially pulled its troops out of Niger this week in a surprise divorce that experts are calling a "blow" to Washington's ambitions for influence in the troubled Sahel region of West Africa. Once-close relations between the two countries saw the US establish large, expensive military bases from which it launched surveillance drones in Niger to monitor myriad armed groups linked to al-Qaeda and ISIL (ISIS). However, those ties collapsed in March when Niger's military government, which seized power in July 2023, cancelled a decade-long security agreement and told the US, which was pushing for a transition to civilian rule, to remove its 1,100 military personnel stationed there by September 15. For months, the US has failed to either fully align with or outright oppose the ruling military, analysts say. On the one hand, Washington seemed ready to maintain defence relations with the new ruling power, but on the other, it felt compelled to denounce the coup and pause aid to Niger.

Human Rights Watch said Thursday that Burkina Faso's security forces last year killed at least 60 civilians in three different drone strikes, which the group says may have constituted war crimes. The West African nation's government claimed the strikes targeted extremists, including jihadi fighters and rebel groups that have been operating in many remote communities. The accusation by the New York-based watchdog were the latest in a string of similar charges raised by various rights groups. "The government should urgently and impartially investigate these apparent war crimes, hold those responsible to account, and provide adequate support for the victims and their families," HRW said in a new report. A mural is seen in Ouagadougou, Burkina Faso, on March 1, 2023.

In the wake of the COVID-19 pandemic, the World Bank's 2020 Global Economic Prospects forecasts a baseline global GDP contraction of 5.2 percent, making it the deepest global recession in decades. Between 71 to 100 million people are expected to be pushed into extreme poverty, almost half of them in South Asia and more than a third in Sub-Saharan Africa. As a result, since March 2020 over 215 countries and territories have implemented 1,414 social protection measures to respond to the pandemic and ensuing economic crisis. Social assistance programs account for 62 percent of all social protection response measures, half of them being cash-based transfers of some sort. This major shock has revealed the many challenges governments face when attempting to quickly respond to crises in order to protect the poor and vulnerable. Providing timely assistance and support to those households most in need can increase their resilience and reduce the negative impacts of the shock on their short and medium-term well-being. Nonetheless, the lack of readily available and up-to-date socioeconomic data necessary to prioritize shock-responsive social protection measures is an important binding constraint for many governments in developing countries. This paper presents a portion of our work on a larger project with the World Bank to identify the most vulnerable populations in these countries. Having timely access to such information, particularly in data-deprived contexts, can improve the capacity of governments to design and operationalize better and more shock-responsive social protection measures.

Burkina Faso is a multi-cultural and diverse country with a rich history. In this article, we explore how personal names can be interpreted to reflect regional, ethnic appartenance within the country. Then we illustrate how the use of a personal name can affect a black-box Artificial Intelligence – such as OpenAI's DALL-E. This is a first article in our series of blog posts with tag #thisnamedpersondoesnotexist.

French drone strikes have killed nearly 40 fighters earlier travelling on motorcycles near Niger's border with Burkina Faso, France's military said on Thursday. In a statement, the French military called the strikes a "new tactical success" for France's counterterrorism efforts in Africa's Sahel region, named Operation Barkhane. "Intelligence obtained from Nigerien units in contact with the column confirmed that the motorcycles belonged to an armed terrorist group moving between Burkina Faso and Niger," Barkhane said in the statement. "In close coordination with Niger's Armed Forces, the Barkhane force conducted several strikes against the column. Nearly 40 terrorists were neutralised."

PARIS (AP) -- The leader of the Islamic State in the Greater Sahara died of wounds from a drone strike that hit him on a motorcycle last month in southern Mali, in a French-led operation involving backup from U.S., EU, Malian and Nigerien military forces, French authorities said Thursday. The French government did not disclose how they identified him as Adnan Abu Walid al-Sahrawi, whose group has terrorized the region. The claim could not immediately be independently verified. France declared the killing a major victory against jihadists in Africa and justification for years of anti-extremist efforts in the Sahel. French government officials described al-Sahrawi as "enemy No. 1" in the region, and accused him of ordering or overseeing attacks on U.S. troops, French aid workers and some 2,000-3,000 African civilians – most of them Muslim.
