British Prime Minister David Cameron poses with school children as they stand in front of a Sopwith Camel by-plane at the Imperial War Museum in London yesterday as he launches the start of World War I commemorations leading up the 100th anniversary of the outbreak of the war in 2014. Britain will stage events across the country and take thousands of children to visit the battlefields of World War I to mark the centenary of the conflict in 2014, Cameron said.
