A local Central African Republic branch of the Red Cross says that days of clashes in the central region have left at least 37 people dead and many displaced.

The group said violence flared in Alindao, some 100 kilometers (62 miles) east of Bambari on Saturday and Sunday as a faction of the mostly Muslim Seleka rebel group fought with the Christian rebel group known as anti-Balaka.

Alindao priest Severin Ngoumango said no shots have been heard for more than 24 hours.

Central African Republic descended into sectarian conflict in 2013 when the Seleka rebels overthrew the Christian president. The Christian militia retaliated with a backlash against Muslim civilians.

Many remote areas remain outside the government's control. Violence by armed groups has risen sharply since late last year.
