BUJUMBURA, Burundi (AP) — Attackers dressed in police uniforms fired a rocket-propelled grenade at a police general's car in Burundi's capital on Friday, a police chief said. The commander and others with him escaped unscathed but three assailants were killed.

The attack raises the death toll this week to nine people amid continued turmoil over President Pierre Nkurunziza's third term in office.

Bujumbura's police chief, Domitien Niyonkuru, said the attackers fired at police Gen. Christophe Manirambona's regular car but he was in a different vehicle this time. Manirombona is in charge of specialized units within the police, including a counter-insurgency unit.

Niyonkuru said two RPGs and four rifles were recovered and police are investigating the source of the police uniforms.

At least six people were killed in overnight violence in Burundi on Tuesday.

The international community has warned that Burundi is sliding toward chaos since Nkurunziza extended his rule by running for, and winning, a third term that many opposed as unconstitutional.

Nkurunziza's decision to seek a third term has triggered months of violence, including an abortive coup attempt. At least 240 people have been killed since April and about 215,000 others have fled to neighboring countries, according to the U.N.

Both opponents and supporters of the government have been killed in apparent revenge attacks.

Burundi has a history of deadly conflicts between the country's Hutu and Tutsi ethnic groups. Nkurunziza took power in 2005 near the end of a civil war in which 300,000 people were killed between 1993 and 2006.
