Officials in Burundi say a presidential adviser has been wounded in an assassination attempt.

Bonfort Ndoreraho, chief of police in the capital Bujumbura, said Tuesday Willy Nyamitwe was at his home northwest of the capital, Bujumbura, when armed men attacked him late Monday.

Nyamitwe is a presidential adviser in charge of communications

Ndoreraho said one policeman in Nyamitwe's security detail was killed while Nyamitwe himself was wounded in the hand.

Foreign Minister Alain Aime Nyamitwe said on Twitter late Monday that Nyamitwe, who is his brother, "survived another assassination attempt."

Sporadic political violence has plagued Burundi since April 2015, when President Pierre Nkurunziza announced he would seek a third term amid significant opposition.

Hundreds of people have been killed and the U.N. also is investigating reports of torture and rape.
