Pakistan Heavy snow and rain forced the United Nations to ground relief flights to Pakistan's earthquake-hit areas for a second straight day Monday, as former President Bush arrived to begin a tour of the stricken region.
Meanwhile, Pakistani officials said new landslides have blocked roads leading into areas of Pakistani-administered Kashmir where hundreds of thousands of survivors remain heavily reliant on aid groups for food and shelter.
Relief workers are racing to ship aid to the Kashmir territory and surrounding regions, concerned that harsh winter weather will intensify hunger and misery, adding to the quake's toll.
Some 87,000 were killed and another 3.5 million made homeless by the 7.6 magnitude tremor on Oct. 8.
U.N. spokesman Ben Malor said relief flights were supposed to resume Monday, but an extended cold front prompted their cancellation.
"We are watching the situation every moment to see when we can (resume)," he said.
The U.N. flies aid to 186 sites in the quake-affected area.
