Nairobi - Four people, including a child, were killed in grenade attacks in Burundi's capital Bujumbura, which has been wracked by political violence, an official and witnesses said on Sunday.
The four were killed in an attack in a bar in the working class Kinama neighbourhood, said Bujumbura mayor Freddy Mbonimpa.
Among the victims was a young boy selling eggs. Ten others were wounded, said a hospital source.
In another attack, "armed criminals" threw a grenade at a police patrol, injuring eight civilians, said Mbonimpa.
Another grenade was thrown at a military patrol, but no one was hurt.
Burundi has been in crisis since April when President Pierre Nkurunziza ran for and won a controversial third term, sparking street protests, a failed coup, regular killings and a nascent rebellion.
The opposition and the government on Sunday traded mutual accusations over the attacks, though no group claimed responsibility.
