The death toll from the worst flooding Nigeria has seen in a decade has increased to 603. More than 1.3 million people have been displaced by the disaster, affecting 33 of Nigeria's 36 states, according to the nation's humanitarian affairs ministry.
At least 340,000 hectares of land also have been affected, worsening fears of food supply disruptions. Authorities blame the disaster this year on the release of excess water from Lagdo dam in neighboring Cameroon and on unusual rainfalls.
