Grenade attack in Rwandan capital wounds 20

A grenade attack wounded 20 people near an open-air fruit and vegetable market in Rwanda's capital Kigali, police said on Tuesday.

A Reuters witness said some of the victims lost their legs and arms when the grenade exploded as night fell in the Gasabo district of the capital.

"A grenade blast injured around 20 people. We think there was only one grenade," Police Spokesman Theos  Badege told Reuters at the scene of the blast.

Rwanda's capital was hit by a string of grenade attacks in 2010, which the government blamed on two high-ranking army officers now in exile.

One of those, Lieutenant-General Faustin Kayumba Nyamwasa, a former chief of staff and ambassador to India, denied the allegations at the time saying the authorities had staged the attacks and then accused him of being behind them.

The landlocked central African nation suffered at least two more grenade attacks last year. (Reuters).
