Heavy rains pounded Dhaka on Tuesday, preventing a U.S. task force and relief agencies from sending planes with supplies to cyclone and flood victims.

"I have never seen so much water in my life," said Lt. Allen Crawford, stepping from one of the four C-130 transport aircraft at Dhaka airport.The plane had been scheduled to leave for Chittagong port in the morning but was still grounded hours later.

Weather officials said 3 inches of rain fell on Dhaka over six hours Tuesday, submerging vast areas of the city of 7 million people.
