The United Nations has set up three emergency centers in Pakistan to coordinate international relief efforts after an earthquake left more than 30,000 people dead in southern Asia, an official said Sunday. An eight-member team from the U.N. Office for the Coordination of Humanitarian Affairs landed in Islamabad on Sunday and has set up centers at the airport, in Islamabad and in the devastated city of Muzaffarabad, said spokesman Elisabeth Byrs. Officials are coordinating international relief efforts from the centers. Three rapid intelligence-gathering teams also have been deployed and are being led by the global body's population agency, a group of international aid groups and the U.N. Children's Fund, Byrs said. "We have to be quick," she said. Six more senior humanitarian officials will arrive in Islamabad later Sunday, Byrs said.
