A teenage suicide bomber attacked worshippers as they gathered for morning prayers Tuesday at a mosque in Mubi, northeastern Nigeria, killing at least 50 people, police said.
Bloody debris covered the floor inside the mosque in Mubi town in Adamawa state where worshippers had arrived around 5 a.m. Outside, people gathered around the dead.
Police spokesman Othman Abubakar said they were “still trying to ascertain the number of injured because they are in various hospitals.”
While there was no immediate claim of responsibility for the bombing, suspicion immediately fell on the Boko Haram extremist group.
Tuesday’s attack was the first since Mubi town was liberated from Boko Haram insurgents in 2014.
Boko Haram increasingly has been using teenagers or young women as bombers, many of whom have been abducted.
The police spokesman said the young man detonated his explosives Tuesday while mingling among the worshippers.
Boko Haram has been blamed for more than 20,000 deaths during its eight-year-old insurgency. The attacks have spilled into neighboring countries and displaced more than 2.4 million people in the Lake Chad region, creating a vast humanitarian crisis.
