A female suicide bomber on Saturday blew herself up in the northeastern Nigerian city of Maiduguri, killing three people and injuring several others, residents said.

The incident in the Dala Yazaram area of the city happened a day after at least 55 people were killed in attacks in the northeast, including 28 in Maiduguri.

A local resident said he saw two female suicide bombers enter the neighborhood of Dala Yazaram, some six kilometers (four miles) from the city but one of them was stopped by people nearby while the other blew herself up.

A spokesman for the National Emergency Management Agency (NEMA) said one person, a member of the civilian vigilante group assisting the military in the fight against Boko Haram, was killed and 10 injured in the blast.

"Four female suicide bombers at about 7:45am today in the morning attempted to enter a Dala Ajeri area of Maiduguri but were intercepted by the civilian JTF (joint military task force)," Sani Datti said in a statement.

"Three of the female suicide bombers detonated the explosions in their bodies immediately and the fourth one was intercepted but later died," he said.

He said six of the injured had been treated and discharged from the hospital.

Although no group has claimed responsibility for the blast, immediate suspicion fell on the Boko Haram takfiri group.

Maiduguri has now been hit seven times this month, killing a total of 79 people, according to an AFP tally, underscoring an increased risk to civilians after similar strikes in neighboring states and near the capital, Abuja.

On Friday, two separate explosions ripped through two mosques in Maiduguri and nearby Yola, capital of Adamawa state, leaving at least 55 worshippers dead and more than 100 injured the Imam had finished a sermon to inaugurate the new mosque.
