YAOUNDE, Oct. 27 (Xinhua) -- At least 10 people were killed in an attack by suspected ex-rebeL Seleka Thursday morning in Grimari in the center of Central African Republic (CAR), security sources told Xinhua.

The sources said the attack took place when the armed group raided Grimari town, 200 km east of capital Bangui and killed for unknown reasons at least 10 inhabitants and injured a dozen of others.

The armed group is suspected to be Union for Progress in CAR (UPC), a faction of ex-rebel Seleka who took power in March 2013, and left in January 2014.

Due to panic, many people in the town chose to take refuge in surrounding communities.
