Local leaders are calling for government protection

(CNN) Twin bombings killed at least 31 people at a market in Madagali, Nigeria, on Friday in an apparent suicide attack carried out by two females, a military spokesman said.

The "female bombers detonated an IED (improvised explosive device) inside a local market," according to a tweet from the National Emergency Management Agency in Nigeria.

Residents of Madagali, in northeast Nigeria's Adamawa state, said the explosions also resulted in numerous injuries.

"The military are in full control of the security situation in the area so there is no security threat," said military spokesman Maj. Badare Akintoye.

Madagali is located on the border with Borno state, the birthplace of the militant group Boko Haram, and has incurred many attacks and abductions since the military retook the area from the militants in 2015.
