Britain's Queen Elizabeth II and Prince Philip take part in a service of Commemoration in London's St. Paul's Cathedral, Friday Oct. 9, 2009, to mark the end of combat operations in Iraq. Britain's combat operations in Iraq formally ended on April 30, six years after the US-led invasion to topple Saddam Hussein in March 2003. During that time, more than 100,000 members of the armed forces and civilian personnel served in Iraq and 179 British servicemen and women were killed.(AP Photo/Kieran Doherty, pool)
