British Defence Secretary Philip Hammond arrives at Downing Street in central London on August 27, 2013. Britain's armed forces are drawing up contingency plans for military action in Syria, Prime Minister David Cameron's spokesman said on August 27, but no decision had been made about what action may be taken. Cameron will decide later on August 27 whether to recall parliament from its summer recess to debate a possible military intervention in the wake of a chemical weapons attack that Washington, London and Paris believe was carried out by the Syrian regime, Downing Street said.
