Russian forces conducting exercises off the eastern coast of Kamchatka spotted an unwelcome spectator -- a Los Angeles-class U.S. nuclear submarine -- and escorted it out of Russia\'s territorial waters. Russian military sources believe the submarine was trying to spy on the command-and-staff exercises that were being conducted under the command of Admiral Viktor Fedorov, commander of the Pacific Fleet. The exercises included 10,000 military personnel, 5,000 civilian specialists, 15 surface vessels and submarines, 10 support vessels, and 20 aircraft. Fedorov gave high marks to the exercises, which were designed to display the results of last winter\'s combat training. (RIA-Novosti)
