Four female suicide bombers at about midnight on Wednesday detonated explosive devices at Usmanti along Muna Garage axis in Maiduguri, the Borno State capital.

Two men were killed due to the explosion while about 16 people sustained injuries.

The spokesperson of the National Emergency Management Agency (NEMA) North-East zone, Abdulkadir Ibrahim confirmed the evacuations of the bodies and the injured who have been taken to a medical facility.

Abdulkadir said: “Rescue and health workers had immediately moved to scene after the alert. The victims have been transported to the state specialist hospital and university teaching hospital in Maiduguri.”

Meanwhile, residents say suicide bombers have now devised a new strategy of knocking on people's doors at night and detonating explosives once the door is opened.

A security officer told PRNigeria that “one of the suicide bombers detonated the explosive device close to the entrance of a security facility in the area.”
