Don't attack Syria, world leaders tell Obama at G20 summit

British PM Cameron says evidence of Sarin gas use in Syria growing; U.S. ambassador to UN says by blocking Syria action, Russia is holding Security Council 'hostage.'
 Russian President Vladimir Putin wants to use the meeting in a seafront tsarist palace to talk Obama out of military action against Syrian President Bashar Assad over a chemical weapons attack which Washington blames on government forces.
 "Military action would have a negative impact on the global economy, especially on the oil price - it will cause a hike in the oil price," Chinese Vice Finance Minister Zhu Guangyao told a briefing.
Britain's Prime Minister David Cameron, though, speaking with the BBC at St. Petersburg, said that Britain has increasing evidence that the Assad regime has used chemical weapons. The evidence against Assad was "growing all the time," he said.
"We have just been looking at some samples taken from Damascus in the Porton Down laboratory in Britain which further shows the use of chemical weapons in that Damascus suburb," he said, referring to the alleged chemical weapons attack of August 21.
France, which is preparing to join U.S. military action, rallied behind Obama.
"We are convinced that if there is no punishment for Mr. Assad, there will be no negotiation," French Foreign Minister Laurent Fabius said before leaving for St. Petersburg.
