The death toll from the 15 May attack on a mosque at Gadan, a community in Gezawa Local Government Area of Kano State, has risen to 21, an official has said.
Residents said they have buried at least 21 victims, mostly aged persons since the incident occurred last week.
A resident of the community, Shafi’u Abubakar, had sprayed the mosque with fuel, locked worshippers inside and set it ablaze. The police initially said Mr Abubakar used a petrol bomb, but locals believed no explosive device was involved.
