"Uzbekistan formally evicted the United States yesterday from a military base that has served as a hub for combat and humanitarian missions to Afghanistan since shortly after the attacks of Sept. 11, 2001, Pentagon and State Department officials said yesterday. In a highly unusual move, the notice of eviction from Karshi-Khanabad air base, known as K2, was delivered by a courier from the Uzbek Foreign Ministry to the U.S. Embassy in Tashkent, said a senior U.S. administration official involved in Central Asia policy."
