In what appeared like the return of insurgency, four suicide bombers died by their own explosive devices Thursday night at Mairanti, a village near Maiduguri, Borno State.
Villagers said an explosion was heard at about 10 pm when they were indoors, but no casualties were recorded except the bombers.
Bashir Garga, North east coordinator of National Emergency Management Agency (NEMA), confirmed the incident on Friday.
According to him, there could be a high infiltration of suicide bombers in the city hence, he advised residents to be extra vigilant.
Mairanti is located around Molai axis of the state capital, which has been a constant target for attacks in the recent times.
In April, nine persons were killed and two police officers injured when suspected Boko Haram insurgents attacked Jiddari Polo area of Maiduguri, the Borno State capital.
