Forty people are feared dead after a dam collapse in northern Nigeria. Officials have yet to verify the death toll.
Authorities say heavy rainfall caused water in a reservoir to overflow, collapsing the dam on Saturday near the city of Gusau, the capital of Zamfara state.
Some 500 houses were swept away.
The dam had been the main source of water for the state capital.
The state governor has asked the Nigerian government to provide aid to the flood victims.
