BUJUMBURA: Witnesses say four people were killed overnight in continuing violence in Burundi’s capital. One witness said on Monday he saw three bodies with bullet wounds following an attack targeting a nightclub in the normally calm neighbourhood of Bwiza. Another witness said a man was killed in a grenade attack in a nearby house. Someone also fired a rocket at the home of the mayor of Bujumbura but the perimeter wall stopped it. Burundi has been wracked by violence since April when President Pierre Nkurunziza announced he would seek a third term in elections he eventually won.
