Four female suicide bombers blew themselves up on Saturday in the northeastern Nigerian city of Maiduguri, injuring 10 people and killing a member of the civilian vigilante group who has been aiding the military in their fight against Boko Haram militants, reported the National Emergency Management Agency (NEMA).
The incident occurred as the women were stopped by self defence fighters on the outskirts of the city for a full body search, said Sani Datti, spokesman of the NEMA.
"Three of the female suicide bombers detonated the explosives on their bodies immediately and the fourth one was intercepted but later died," said Datti.
The incident came a day after two bomb attacks killed at least 55 people and injured more than 100 in Nigeria’s northeastern regions of Yola and Maiduguri.
No group has claimed responsibility for the attack, however, Boko Haram militants are known to carry out similar attacks in the region.
According to a report released earlier this month by the human rights group Amnesty International, more than 1,600 people have been killed by Boko Haram militants since June, bringing the death toll to about 3,500 this year alone.
Boko Haram militants generally target Nigeria, Cameroon, Niger and Chad and continue to remain a threat to these countries despite the military intervention ordered by Nigerian President, Muhammadu Buhari.
