BUJUMBURA, Burundi (AP) — The United States has sanctioned two Burundi government officials and one rebel leader over violence in the country linked to President Pierre Nkurunziza's extended tenure.

In a statement late Thursday the U.S. Department of the Treasury's Office of Foreign Assets Control said it has sanctioned military commander Marius Ngendabanka, security official Ignace Sibomana and rebel leader Edouard Nshimirimana. The statement says it has sanctioned the three men for engaging in actions or policies that threaten the peace, security or stability of Burundi.

According to the U.N. at least 400 people have died since Nkurunziza run for and won a third term that many say is unconstitutional. The sanctions mean all assets of those named are frozen in the U.S. and U.S. nationals are prohibited from engaging in transactions with them.
