Twin blasts at mosque in northern Nigeria kill at least 24

Police say at least 24 worshipers have been killed in an attack on a mosque in northern Nigeria.

Adamawa State police spokesman Othman Abubakar says an explosion occurred during prayers Tuesday afternoon and many people died as they fled and were caught by a second blast.

Abubakar says the scene in Mubi has been cordoned off by anti-bomb squads and security personnel.

Residents said they saw a young man wearing a suicide vest entering the mosque with the worshipers. One resident said the mosque’s roof was blown off.

Many are blaming the Nigeria-based Boko Haram extremist group for the attack.
