The death toll from massive floods in Pakistan rose to 1,497 on Friday as U.N. chief Ban Ki-moon said the crisis is a "slow-motion tsunami" that is expected to grow.
The number of homeless as a result of flooding has doubled to 4 million.
Ban urged the international community to give more aid during a special fundraising meeting Thursday night.
"Make no mistake," he said. "This is a global disaster, a global challenge. It is one of the greatest tests of global solidarity in our times."
