Hundreds of thousands of Pakistanis have been ordered to evacuate their homes as flood waters threaten several cities in the south of the country.
The flood surge, after weeks of monsoon rains, has breached embankments on the Indus River, inundating villages and swamping vast areas of farmland. Parts of Pakistan have been described as resembling an inland sea.
After threats from Pakistan’s Taliban, the UN is reviewing security for its aid workers helping flood victims.
A US official said militants planned to attack foreigners delivering aid to the millions of people affected by the devastating floods.
