Villagers run to receive relief packages air dropped for flood victims Saturday at Darbhanga district, in the northern Indian state of Bihar. Torrents of water washed away homes, crops and cows, leaving hungry and frightened villagers perched in treetops or on roofs as the death toll rose to at least 186 and 19 million were driven from their homes in recent days from monsoon rains across northern India and Bangladesh.

Lucknow, India ? Helicopters dropped food to almost 2 million marooned Indian villagers Saturday as the death toll from unusually heavy monsoon rains and floods in South Asia rose to more than 225.

The food drops to 2,200 villages cut off by flooding aimed to help desperate residents in the worst-hit eastern parts of India’s Uttar Pradesh state. Umesh Sinha, the state relief commissioner, also said nearly 280,000 acres of rice paddy crops had been destroyed.

In India’s northeastern Assam state, flooding forced rhinos from their habitat at the Kaziranga National Park and their panicked charges killed one person and injured two others, wildlife officials said.

At least 229 people have been killed in India and neighboring Bangladesh, and 19 million driven from their homes in recent days. The South Asian monsoon season runs from June to September as the rains work their way across the subcontinent, a deluge that scatters floods and landslides across the region and kills hundreds of people every year.

The number of dead in Bangladesh rose to 81 Saturday, up from 65 a day earlier, the country’s information ministry said. Raging floodwaters have battered 38 out of 64 districts in the delta nation of 145 million people.

Fakhruddin Ahmed, head of Bangladesh’s military-backed interim government, visited the northwestern district of Sirajganj on Saturday. Despite the devastation, he said the government had enough food and medicine to distribute and foreign assistance wasn’t yet needed.

One person looking for that help was 45-year-old Aleya Begum, who took shelter on an embankment with more than 50 other families after their homes washed away in Pabna, 75 miles north of the capital, Dhaka.

She said the group was short of drinking water.

“I’ve lost everything. We need help from the government to survive,” Begum said.

Low-lying areas around Dhaka were under neck-deep water, and many residents were using boats to travel around. Government meteorologists said water levels in Dhaka continued to rise.

Flooded rivers started to recede Saturday in the Indian state of Assam – but there was no such respite in Uttar Pradesh and Bihar states.

Mayawati, Uttar Pradesh’s top elected official, said India and neighboring Nepal had signed a treaty in 1996 to solve the annual flooding by building dams and hydropower projects, but the projects have not yet begun.
