The United Nations has appealed for $365 million to help millions of Pakistanis affected by floods caused by heavy monsoon rains. Humaira Mehboob, a spokeswoman for the U.N.'s humanitarian arm, said Sunday the money would be used to help over 5.4 million people in the provinces of Sindh and Baluchistan over the next six months. The U.N. says the floods have killed 248 people in Pakistan and damaged or destroyed some 665,000 homes. They began early last month, but heavy rains have compounded them recently and hampered relief efforts. Pakistan often experiences flooding from monsoon rains that lash much of South Asia from June to September.
