Attempts have been made to rescue victims buried in the rubble with excavators.
In Nigeria, at least 21 students died and around 70 were injured after a school collapsed in the central part of the country on Friday, says the Red Cross.
The cries for help of those buried there could be heard from the ruins. Excavators were used to try to rescue the victims, and the students’ parents desperately searched for their children.
An injured person was being treated at the hospital Wulliya Ibrahim.
