The United States has withdrawn its nuclear weapons from the United Kingdom more than 50 years after it first deployed atomic bombs there, a watchdog group says. The withdrawal was reported this week by the Federation of American Scientists, a public policy group based in Washington, and was confirmed by a Western government official to The Associated Press. The FAS report says that 110 nuclear bombs once deployed at the Royal Air Force's Lakenheath air base, 112 kilometers northeast of London, are now gone. It is unclear when they were removed. The US and British governments declined to comment on the report.
