At least five people were killed and more than 30 others injured when a bomb exploded inside a mosque during prayers in Maiduguri, northeastern Nigeria, police said Wednesday night.
Authorities believe the blast was a suicide attack, citing recovered fragments of a suspected explosive vest. Security forces have cordoned off the area and are searching for additional devices.
No group has claimed responsibility, though such attacks have previously been linked to Boko Haram, which has waged a long-running insurgency in the region.
