Afghanistan today donated one million dollars to help the victims of unprecedented floods in neighbouring Pakistan. Finance minister Hazrat Omar Zakhailwal handed the cheque to Pakistani ambassador Mohammad Sadiq at the end of a press conference in Afghan capital Kabul. Torrential monsoon rain triggered catastrophic floods which have affected a fifth of the country, wiping out villages, rich farmland, infrastructure and killing an estimated 1,600 people in the nation's worst ever natural disaster. The United Nations last week launched an immediate appeal for 460 million dollars to cover the next 90 days and UN chief Ban Ki-moon visited Pakistan at the weekend, calling on the world to quicken its aid pledges.
