A child suicide bomber detonated his explosives, killing himself, two other bombers and six people in Nigeria's northeast, in the latest bloodshed blamed on Boko Haram Islamist group, the army said on Monday.
The attack in Beninsheikh in Borno state happened around 8.30 pm on Sunday when three suspected suicide bombers aged between 10 and 15 years, were stopped for security screening by civilian vigilantes in the area, Colonel Sani Usman said in a statement.
He said one of the bombers, who was strapped with explosives, detonated the bomb, causing the "death of nine people while 24 others sustained various degrees of injuries."
Usman said the three suicide bombers were among the dead.
"The security and emergency management agents have mobilised to the scene. The bodies have been evacuated and all those injured are receiving medical attention," he said.
Suicide bombings -- many by young boys and girls -- have fast become Boko Haram's preferred method of inflicting civilian casualties since it control of captured territory to a renewed military offensive by the military in recent months.
Nigeria's President Muhammadu Buhari has given his military commanders until the end of the month to end the six-year violence.
