UN Chief Ban Ki-Moon: Pakistan Floods Are Worst Disaster I've Ever Seen

U.N. Secretary-General Ban Ki-moon said Sunday he has never seen anything like the flood disaster in Pakistan after surveying the devastation and urged foreign donors to speed up assistance to the 20 million people affected..."This has been a heart-wrenching day for me," Ban said after flying over the hard-hit areas with President Asif Ali Zardari. "I will never forget the destruction and suffering I have witnessed today. In the past I have witnessed many natural disasters around the world, but nothing like this."
