Pakistan health authorities have expressed concern about the risk of water-born diseases spreading in flood-ravaged areas. With large swathes of the country covered in murky flood waters, the death count surged past 1,200 on Friday. The United Nations and Pakistan have jointly issued an appeal for 160 million US dollars in emergency funding to help the 3.3 million people affected by the floods. More than one million homes have been damaged, and the devastation is believed to have caused 10 billion dollars in damage so far. Planes carrying fresh supplies have been surging across a humanitarian air bridge to Pakistan's capital.
