The International Committee of the Red Cross on Sunday appealed for 7.8 million dollars in emergency funding to help victims of the powerful earthquake that rocked southwest Pakistan this week. The ICRC said that the money would be used to step up the relief effort being carried out by its teams and those from the Pakistan Red Crescent Society. Up to 300 people were killed and tens of thousands more left homeless when a 6.4-magnitude quake struck before dawn in mountainous Baluchistan province on Wednesday, flattening mud-brick houses as people slept. Some local people in remote villages have complained that aid has been slow in reaching them, particularly protection from sub-zero nighttime temperatures. Health officials have warned of the spread of deadly diseases among children. The ICRC's head of delegation in Islamabad, Pascal Cuttat, said: "Our priority will be to provide shelter as winter sets in. "Because of continuing aftershocks, many people decided to sleep outdoors, at altitudes of 2,000 to 2,500 metres (6,500 to 8,200 feet).
