Hundreds of people have been left homeless after heavy floods swept through north-eastern Nigeria's Damaturu city on Tuesday.

The floods were the worst to hit the city in 20 years, said Musa Jidawa, a senior official with the government's emergency management agency after visiting the affected areas.

Local media report that between 100 and 200 homes were destroyed. Shops were also swept away.

"We have gone round for first-hand information to determine areas of immediate needs and intervention,” Mr Jidawa was quoted by the Nigeria News Agency as saying.
