Muslim rebels have killed at least 11 people seeking refuge in a church in the capital of Central African Republic.

Witnesses to the attack Wednesday in Bangui say as many as 30 were killed.

They say Muslim gunmen threw grenades and fired bullets into the church compound.

It was the worst attack blamed on Muslims since their Seleka rebel group was ousted from power in January.

Chaos and violence has run rampant in CAR since Seleka rebels seized power last year. They began looting and killing Christians, who formed a militia that launched reprisals against Muslim civilians.

Thousands of Muslims have fled for their lives from Bangui.
