US combat pilots in Afghanistan are flying to Pakistan to provide aid to the millions affected by devastating floods and to improve America's image. Continuous Torrential monsoon rains have lead to catastrophic floods in the country. According to UN, 13.8 million people are affected by the floods. Entire villages have been washed away. Parts of the country, such as the northwest Swat valley which for years was paralysed by Taliban insurgency, are cut off from the outside world. An estimated 1,600 people have died. The government says the international community has promised 92 million dollars. The White House said that US helicopters have helped to save more than 1,000 lives in Pakistan. Washington has provided 35 million dollars in aid. Meanwhile, the Pakistan President Azif Ali Zardari has returned to his flood ravaged country after a foreign tour that has been widely criticised. Mr Zardari is expected to visit some of the areas devastated by flooding. His opponents say he should have done that days ago instead of travelling abroad. The floods have so far killed nearly 1600 people.
