BUJUMBURA: A series of explosions hit Burundi's economic capital, killing at least three people and injuring dozens on Monday (Tuesday in Manila) evening, police and media reports said, the latest in a string of attacks. The blasts in Bujumbura followed a deadly grenade explosion in a bar in the capital Gitega on Sunday and a series of mortars launched on Burundi's international airport on Saturday night. At least two grenades exploded in a bus parking lot in Bujumbura's city center on Monday at around 7 p.m. (1 a.m. in Manila), a police source and eyewitnesses said.
