Geneva ? Governments and other donors told the United Nations on Wednesday they were pledging an additional $580 million for Pakistani earthquake victims, but U.N. officials said it was unclear how much would be earmarked for immediate relief efforts with the bitter Himalayan winter looming.

The U.N. had requested $550 million in immediate aid on the eve of the donors’ conference in Geneva, but officials said some of the new money might go to other humanitarian organizations or future reconstruction projects.

So far, $111 million has been specifically earmarked for the U.N. appeal, top U.N. relief coordinator Jan Egeland told reporters after the meeting.
