U.S. emergency relief teams continued to arrive in Peshawar to help, the U.S. State Department said. The U.S. Agency for International Development has committed $55 million in aid to international organizations and nongovernmental organizations, it said. The United States has provided more than 435,000 meals. This assistance is in addition to U.S. military efforts, which include rescue airlifts, food supplies and other deliveries provided by the Pentagon.

Of the total, $20 million will be used to expand humanitarian operations farther south as the flood zone expands, Mark Ward, acting director of the Office of Foreign Disaster Assistance, told reporters Tuesday.

Islamic militants, however, called on the Pakistani government to reject any aid provided by the United States for flood relief. "For the sake of God, don't accept donations from the U.S. because they are our enemies," said Azem Tariq, spokesman for Pakistan Taliban. "Whatever amount the U.S. will give as donation, we will give the government of Pakistan more."
