YOLA, Nigeria—Explosions in and around a mosque in northeast Nigeria killed at least 27 people on Tuesday, a hospital official said, in the latest in a spate of attacks by militants in the region.
The blasts in the town of Mubi bore the hallmarks of Islamist militant group Boko Haram, which has waged an insurgency in Africa’s most populous country since 2009 and often deploys suicide bombers in crowded places.
