Anti-War Protesters Gather Outside Downing Street

LONDON, ENGLAND - NOVEMBER 28: An anti-war protester during a day of protest outside Downing Street against the possible British involvement in the bombing of Syria at Downing Street on November 28, 2015 in London, England. UK anti-war organisation, Stop the War Coalition, organised the protest in response to the proposed vote in Parliament by David Cameron to involve British forces in the bombing of ISIS targets in Syria. A similar protest in February 2003 against the British involvement in Iraq attracted a reported 2 million people to the streets of London. (Photo by Chris Ratcliffe/Getty Images)
