At least 22 people were killed over Wednesday and Thursday in clashes between the predominantly Muslim Seleka militias and Christian anti-balaka militiamen in northern (Central African Republic), a source with the African-led force in the war-torn country said Friday.

The violence erupted Wednesday when anti-balaka militiamen attacked Seleke bases in Batangafo, 300 kilometers north of Bangui, prompting the Muslim militiamen to fight back, the source working with the African-led International Support Mission to CAR told media outlets.

"The clashes, which lasted for two days, left 22 dead and several others wounded, mostly civilians," the source said, without giving further details.

The clashes came one week after the signing of a ceasefire agreement between the two sides in Brazzaville, DR Congo, under which both parties pledged to stop hostility and ensure the free movement of goods and people.

The country was plagued by tit-for-tat sectarian violence between Christian anti-balaka militias and the seleka fighters.
