A court in Senegal convicted former Chadian dictator Hissène Habré of crimes against humanity committed during his rule from 1982 to 1990, and sentenced him to life imprisonment on May 30. He was found guilty of sex slavery, rape and the ordered killings of an estimated 40,000 people. The trial marks the first time a court with backing from the African Union has tried a former ruler for human rights violations, and also the first time a former African head of state was found guilty by an another African country. Habré has 15 days to appeal the sentence. Human Rights Watch lawyer Reed Brody, who initiated the trial, stated: "This verdict sends a powerful message that the days when tyrants could brutalize their people, pillage their treasury and escape abroad to a life of luxury are coming to an end. Today will be carved into history as the day that a band of unrelenting survivors brought their dictator to justice."

President Barack Obama formally notified Congress Oct. 14 that 90 US troops have been mobilized to Cameroon—the first contingent of a 300-strong force to assist in the struggle against Boko Haram. The force will conduct airborne intelligence, surveillance, and reconnaissance, but will not participate in ground combat operations (except in self-defense). Unarmed surveillance drones will also be deployed. The Pentagon said the move came at the invitation of Cameroon's government, which has been headed by strongman Paul Biya since 1982. Cameroon is part in a joint regional task force to fight Boko Haram along with Chad, Niger and Benin.

At least five suicide bombers on Oct. 10 targeted a village in Chad that is home to thousands of Nigerians who have fled Boko Haram violence, killing at least 36 people and wounding about 50 others in co-ordinated attacks. Authorities blamed Boko Haram for staging the attacks in the village of Baga Sola, near the Nigerian border. Nearly half of the dead resulted when two female suicide bombers hit the village market when it was at its busiest. The following day, two female suicide bombers carried out the attacks in the Cameroon village of Kangaleri, again targeting a market district and killing nine. Both western Chad and northern Cameroon hosts thousands of Nigerian refugees. Another 1.5 million are internally displaced within Nigeria. (AFP, CBC, Sahara Reporters, Anadolu Agency)

The Extraordinary African Chambers on Sept. 3 confirmed that war crime accusations have been filed against Chad's President Idriss Deby. The special tribunal in Senegal is overseeing the case against the former president of Chad, Hissène Habré (BBC profile), who was accused of crimes against humanity, war crimes and torture. A Senegalese lawyer, Mbaye Jacques Ndiaye, filed the charges against Deby to hold him responsible for the role he played in perpetuating the alleged crimes of his predecessor while he served as Habré's army chief.

(See map) That same day, 42 lost their lives in a series of blasts at two bus stations in Gombe, northeast Nigeria. A new five-nation force—from Nigeria, Niger, Chad, Cameroon and Benin—is due for deployment to fight Boko Haram by month's end.

But the day after the arrest ot Baana Fanay, two new suicide bombings in N'Djamena kiilled at least 11, including five police officers.

An advance unit of hundreds of Chadian troops, backed up by a column of tanks, arrived at Cameroon's northern border town of Kousseri Jan. 17, greeted with cheers by local residents terrorized by Boko Haram. The intervention force, approved by Chad's parliament, is to number in the thousands. Days earlier, most of the residents of nearby Kolofata were forced to flee after an attack by Boko Haram. Cameroon troops killed 143 insurgents in a gun battle that lasted more than four hours, the army said. Boko Haram leader Abubakar Shekau this month threatened Cameroon's President Paul Biya in an online video. Biya sent some 1,000 troops to the border to fight Boko Haram after the wife of deputy premier Amadou Ali was captured in July by suspected militants. A French-led initiative calls for Nigeria, Niger, Cameroon and Chad to contribute 700 troops each to a multinational force against Boko Haram.

Authorities in Mali said July 31 that a once-powerful jihadist leader has been arrested by French military forces in the northern desert town of Gao. Yoro Ould Daha was a commander of the Movement for Unity and Jihad in West Africa (MUJAO), which controlled Gao for nearly a year before the French intervention of 2013. Ould Daha was the MUJAO commander who announced the death of French hostage Gilberto Rodriguez-Leal, who was captured in November 2012 while traveling in Mauritania and Mali. He also took responsibility for the abduction of five humanitarian workers who were later released. (AP, July 31)
