UN Issues Flash Appeal For $160 Million To Help Pakistan With Floods.

The United Nations and Pakistan issued an appeal Tuesday for $160 million in emergency funding to help millions affected by record-breaking floods that have killed more than 1,150 people since mid-June.

U.N. Secretary-General Antonio Gutteres said Pakistan's flooding, caused by weeks of unprecedented monsoon rains, were a signal to the world to step up action against climate change.

'Let's stop sleepwalking toward the destruction of our planet by climate change,' he said in a video message to an Islamabad ceremony launching the funding appeal. 'Today, it's Pakistan. Tomorrow, it could be your country.'

More than 33 million people, or one in seven Pakistanis, have been affected by the catastrophic flooding, which has devastated a country already trying to revive a struggling economy.

The National Disaster Management Authority on Tuesday warned emergency services to be on maximum alert, saying flood waters over the next 24 hours could cause further damage.

Rescuers continued to evacuate stranded people from inundated villages to safer ground. Makeshift tent camps have sprung up along highways.

Meteorologists have warned of more rains in coming weeks.

'The situation is likely to deteriorate even further as heavy rains continue over areas already inundated by more than two months of storms and flooding. For us, this is no less than a national emergency,' Pakistani Foreign Minister Bilawal Bhutto-Zardari said Tuesday, urging the international community to give generously to the U.N. appeal.

'Since mid-June, in fact, Pakistan has been battling one of the most severe, totally anomalous cycles of torrential monsoon weather,'...
