Residents gather near the scene of the explosion at a mosque in the Gamboru market in Maiduguri on December 25, 2025. An explosion ripped through a mosque in the northeastern Nigerian city of Maiduguri and killed at least seven worshippers on December 24, 2025, witnesses and security sources told AFP. No armed groups immediately claimed responsibility for what anti-jihadist militia leader Babakura Kolo said was a suspected bombing. Maiduguri is the capital of Borno state, home to a years-long insurgency by jihadist groups Boko Haram and an offshoot, Islamic State West Africa Province, though the city itself has not seen a major attack in years.
