A suicide attack killed at least nine people and injured 15 in a village in Nigeria's northeastern Adamawa State on Tuesday, according to witness reports.
"A suicide bomber detonated a bomb in Garkida, killing at least nine people," villager Abu Fagge told Anadolu Agency.
Garkida village in Adamawa, where the bombing occurred, was newly liberated from Boko Haram and that fighting still continues between Nigerian army forces and the militants.
Defence spokesman Chris Olukolade confirmed the bombing saying "Yes, there was a suicide bomb attack," but avoided giving numbers about casualties.
Last Saturday, seven people were killed in the capital of Yobe State in northern Nigeria, when a teenage suicide bomber blew herself up at a bus station in a busy market place.
Boko Haram has been fighting a six-year insurgency in a bid to establish a state of its own in northern Nigeria and killed thousands of people and caused about 1.5 million to flee their homes.
A recent offensive by Nigerian army was backed by neighbouring Niger and Chad, recapturing most of the territory in Adamawa, Borno and Yobe states and forced Boko Haram to retreat.
