Britain Charges 5 on Terrorism Counts LONDON - British police officials said on Thursday that they had charged five people with terrorism offenses but insisted that the accusations were not related to the Olympic Games opening here on July 27 amid a shortage of civilian security personnel that has forced an expanded military deployment. The counterterrorism command at Scotland Yard said three men from London were charged late Wednesday with offenses that involved travel to Pakistan for what was described as terrorism training between July 2010 and this month. A woman was charged with possessing a computer USB storage device that was said to have contained material used in terrorism, and a fifth man was charged on separate offenses. The three men from London included Richard Dart, who had appeared in a British television documentary program relating to his conversion to Islam. The five people were to appear in court later on Thursday. The development followed a rash of security alarms this month during which police arrested 13 people in a 24-hour period in London and the English Midlands further north. At the time, the unusually high number of detentions reflected concerns that when the 2012 Olympics open in London, they could become the highest-profile targets since the 2001 attacks in New York and Washington. Three of the people arrested were seized in east London close to the location of the Olympic stadium and village. Despite official assurances that the arrests were not related to the security of the games, preparations for the event have been tarnished by the failure of a G4S, a huge global security firm, to recruit all of the guaranteed 10,400 personnel it promised to deploy. The chief executive of the company, Nick Buckles, acknowledged before a parliamentary panel on Tuesday that the shortfall represented a "humiliating shambles" for his company. The Army promised an extra 3,500 soldiers, some just back from the war in Afghanistan, to patrol the games, bringing the total military commitment to 17,000. Another potential disruption emerged on Thursday with plans among thousands of staff at the Home Office, including airport immigration workers, to strike to press demands for better working conditions. At a news conference on Thursday during a visit to Kabul, Afghanistan, Prime Minister David Cameron said he did not approve of the strike plan. "I do not believe it will be right, I do not believe it will be justified," he said, according to The Press Association news agency. Labor union leaders planned to meet Thursday to decide how to proceed after a vote among union members in favor of action to protest threatened layoffs and limits on pay increase.
