Kerala floods: Around 800,000 sheltering in camps and over 350 dead as rescuers rush to provide drinking water

Around 800,000 people have been displaced and over 350 have died in the worst flooding in a century in southern India, as authorities rushed to bring drinking water to the worst affected areas.

At least two trains carrying about 1.5 million litres of water were moving to the flooded areas in Kerala state from the neighbouring states of Madhya Pradesh and Maharashtra on Sunday.

Thousands of rescuers were continuing efforts to reach out to stranded people and get relief supplies to isolated areas by hundreds of boats and nearly two dozen helicopters.

Weather conditions have now improved considerably and the nearly 10,000 people still stranded are expected to be rescued by the end of Monday.

Meanwhile, an estimated 800,000 people were sheltered in some 4,000 relief camps across Kerala.

Weather officials have predicted more rains across the state until Monday morning.

The downpours that started on August 8 have triggered floods and landslides and caused homes and bridges to collapse across Kerala, a picturesque state known for its quiet tropical backwaters and beautiful beaches.

Officials estimate that more than 6,200 miles of roads have been damaged.

One of the state's major airports, in the city of Kochi, was closed on Tuesday due to the flooding and is scheduled to remain closed until August 26.

The Indian government said a naval air base in Kochi will be opened for commercial flights starting on Monday morning.

India's prime minister Narendra Modi inspected the flooded landscape from a helicopter on Saturday and met with the state's top officials, promising more than 70 million US dollars in aid.

While the central government has dispatched multiple military units to Kerala, state officials are pleading for additional help.

Officials have put initial storm damage estimates at nearly three billion US dollars.

At least 250 people have died in the flooding in a little over a week, with 31 others missing, according to Mr Kurian.

More than 1,000 people have died in flooding in seven Indian states since the start of the monsoon season, including over 350 in Kerala.
