The U.N.'s top human rights body is discussing the rising violence in Burundi, with the United States leading a diplomatic push aiming to deploy a mission of experts and launch an investigation of abuses.

Thursday's special session of the Human Rights Council comes just days after at least 87 people were killed in attacks on military facilities in the capital, Bujumbura. It also comes weeks after Burundi was elected as a member of the 47-member rights body based in Geneva.

Burundi has been in turmoil since the April announcement that President Pierre Nkurunziza would seek a third term in office, which he won in a disputed election in July. More than 300 people have been killed, about 215,000 others have fled.

U.N. officials fear Burundi is heading toward civil war.
