Queen Elizabeth II led Britain's annual ceremony for the country's war dead Sunday, honoring them with a moment of silence as the military reported that more than 200 British soldiers have been killed in combat in Afghanistan.

As Big Ben chimed 11 a.m., the queen joined thousands of troops, veterans and civilians in the traditional two-minute silence on Remembrance Sunday beside London's major war memorial, the Cenotaph. The silence was broken by a single artillery blast and the sound of Royal Marine buglers playing "Last Post."

The remembrance service is held every year on the nearest Sunday to the anniversary of the end of World War I at 11 a.m. on Nov. 11, 1918, and now pays tribute to the dead in all conflicts, including World War II, Iraq and Afghanistan.
