Heavy rain and snow in Pakistani Kashmir has grounded relief flights to survivors of last year's earthquake for a third consecutive day. The bad weather also forced former President George Bush, the father of the current president, to postpone a flight to the regional capital, Muzaffarabad.

The elder Mr. Bush is visiting Pakistan in his role as a United Nations special envoy for earthquake relief. He greeted earthquake refugees Tuesday at a tent camp on the outskirts of Islamabad. On Monday, he discussed aid and reconstruction efforts with Pakistani President Pervez Musharraf.

U.N. officials say the world body is still far short of the $500 million it needs to sustain relief operations for the three million people made homeless by last October's earthquake.
