ABUJA, Nigeria (AP) — At least eight worshippers were killed and 16 others injured early Wednesday morning after a man attacked a mosque with a locally made explosive in northern Nigeria’s Kano state, resulting in a fire outbreak, the police said.

The suspect, a 38-year-old local resident, confessed that he attacked the mosque in Kano’s remote Gadan village “purely in hostility following (a) prolonged family disagreement,” police spokesman Abdullahi Haruna said in a statement on Wednesday.

Eight of those injured died later in a hospital, Haruna later told local Channels Television on Thursday. Four children were among the injured worshippers, although it was not clear if any of the children died.

The incident caused panic in Kano, northern Nigeria’s largest state, where periodic religion-related unrest has occurred over the years, sometimes resulting in violence.
