Thirty people were killed and over 50 others were injured when violence erupted Wednesday in the Central African Republic, the U.N. said.
Fighters with the former Seleka rebel group attacked the town of Kaga-Bandoro before eventually being repelled by U.N. peacekeepers, who killed 12 of the rebels. Nine civilians were also among the dead.
The attack was likely retaliation for a Tuesday killing of a suspected former Seleka member, the peacekeeping mission said in a statement.
Many ex-Seleka rebels, a group that rose to power in 2013, have reorganized in Kaga-Bandoro after fleeing the capital of Bangui two years ago.
Sporadic clashes between rebel groups in several villages in the Central African Republic are threatening the nation’s fragile peace process.
