Video - Nigeria may declare national disaster as flood death toll rises to 100

Authorities in Nigeria say more than 100 people have been killed in the floods across the country in the past two weeks. Heavy rains have caused the country's two major rivers -- the Niger and Benue -- to overflow. Dozens of communities have been completely submerged, thousands of people displaced and vast swathes of farmlands destroyed. Rural areas are the worst hit. The government is urging residents living along waterways to relocate to higher places. It's also considering declaring a state of emergency to free up funding and ensure a more effective response. Nigeria is battered by floods almost every year. Analysts blame it on a lack of proper town planning, blocked waterways and poor drainage.
