Flooding in eastern Nigeria has killed at least 10 people and displaced thousands of others.

Emergency officials say the flood resulted from the release of water from a dam in neighboring Cameroon.

The head of the agency in Nigeria's Adamawa state, Shadrach Daniel, told the French news agency Monday that flooding swept away more than 40 villages and that in addition to the 10 people killed, others remain missing.

He said water was released from the Lagdo dam on Friday in neighboring Cameroon after officials there warned Nigeria several weeks ago.

Another agency official said that heavy rainfall in the rural region also contributed to the deadly deluge. He said many people remained trapped by the flooding Sunday and that thousands have been displaced.

Nigeria is experiencing its annual rainy season, with torrential rains fall throughout the nation.

The flood deaths in Adamawa come after four people were killed by heavy rains in Bosso and Zungeru areas of Niger state.

Recent floods also killed more than 60 people in Plateau state and destroyed several bridges.
