Abuja: At least 11 people were killed and two churches razed by gunmen who stormed two communities in central Nigeria’s Plateau State, local media cited security sources as saying.

Six civilians and five security personnel lost their lives in the attack on Gako and Tanjol communities, both located in the restive Riyom area.

Police said only six dead bodies had been found so far.

The cause of the attack was still unknown, although residents said it might be a reprisal attack following unsolved ethnic-religious violence plaguing the state.

According to state police spokesperson Dominic Esin, five other people were injured as the unknown gunmen went on a rampage and razed two churches.

No group has so far claimed responsibility for the attack.

Nigeria is currently grappling with security challenges carried out mainly by the insurgency of Boko Haram, which seeks to enshrine the Islamic Sharia law in the constitution.
