The United Nations has made a fresh appeal for aid for survivors of the Pakistan earthquake. It will urge 65 nations gathering in Geneva today for a donors conference to come forward with more money. So far the UN has only received a third of the 453 million euros pledged. Within a month, winter weather will make many areas inaccessible, and experts fear more people could be killed than during the earthquake.With the known death toll at more than 53,000, relief workers are fast running out of time to get hundreds of thousands of people under shelter and treat countless injured who were still untended. Up to three million people must be sheltered and fed through the winter and more tents are needed than the world can supply. Talks with India are scheduled for Saturday on the highly sensitive issue of opening up its border with Pakistan to help relief efforts. The quake killed 1,300 people in Indian Kashmir.
