People in the town of Ibadan, Nigeria, are surveying the damage after devastating flash flooding caused by heavy rains.
More than a 100 people were killed when high water levels caused a dam to overflow into the town, washing away many homes and damaging bridges.
Nigeria's emergency agency has warned there could be more flooding due to insufficient drainage.
