Twenty-six people were killed and 28 injured Saturday afternoon in a suicide bomb attack inside a mosque in Maiduguri, the capital and largest city of Borno state, Aderemi Opadokun, the Borno State Police Commissioner told CNN.
Nobody has claimed responsibility for the attack, which occurred while worshipers were inside the mosque.
The attack came one day after Muhammadu Buhari was sworn in as the West African nation's president.
Earlier Saturday, the Islamist extremist group Boko Haram launched a rocket-propelled grenade attack on Maiduguri.
