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 Sunday.
The four were killed by an attack late Saturday 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, according to a hospital source.
In another attack Saturday "armed criminals" threw a grenade at a police patrol, injuring eight civilians, Mbonimpa said.

Another grenade 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.
