NAIROBI: Gunmen wounded a senior army commander in western Burundi, a military spokesman said on Sunday, with at least four killed in following clashes. Colonel Serge Kabanyura was shot when gunmen opened fire in an ambush as he was driving on Saturday to the capital Bujumbura, some 20 km from the city, said army spokesman Gaspard Baratuza. The area is a stronghold of the former rebels from the 1993-2006 civil war, the National Liberation Forces, who oppose the third term for President Pierre Nkurunziza.
