Uzbekistan formally ordered the United States to leave an air base that has been a hub for operations in Afghanistan in protest over a predawn United Nations operation on Friday to spirit out refugees who had fled an uprising in Uzbekistan in May, senior State Department officials said Saturday.
The officials said Uzbekistan had given the United States 180 days to close the base, which has played a central role in rooting out fighters of the Taliban and Al Qaeda and in carrying out relief operations.
