Thousands affected by Nepal flood

Many flood victims are suffering from diseases

Nearly 30,000 people are reported to have fled their homes after a dam collapsed in south-eastern Nepal leading to flooding in the area.

The police say they are trying to rescue the stranded people, but the high water levels are making airlifting them difficult.

The Koshi dam on the Saptakoshi river in Sunsari district collapsed on Monday afternoon after breaching embankments.

Many flood victims have taken shelter in school and college buildings.

The police say at least three people have drowned in the floods.

A number of villages have been inundated, a police officer said. "People stranded on the roofs of their houses are being rescued by boat rescue teams," he added.

Traffic on a highway linking eastern Nepal with its western part has been affected after flood waters damaged a section of the road.

Many of the flood victims who are suffering from diarrhoea and fever have been taken to the district hospital, a police official said.

About 28 million people were affected by the floods in India, Bangladesh and Nepal last year, in which more than 400 people died.
