BANGUI: More than 20 people were injured when grenades were thrown into a concert in the capital of the chronically unstable Central African Republic, while revenge attacks later left three people dead, the UN peacekeeping force and a local official said Sunday, reports AFP.

The grenade assault late Saturday saw two unidentified attackers hurl a grenade at a cafe called “On the Crossroads of Peace” during a concert by local singer Ozaguin, said Herve Verhoosel, spokesman for the UN peacekeeping force MINUSCA.

The cafe is located near the PK5 majority Muslim district of Bangui, once a Muslim rebel bastion, and now home to several armed groups.
