Obama to make G20 push for Syria strike

SAINT-PETERSBURG: World leaders meet Thursday at a G20 summit in Russia where US President Barack Obama will strive to bridge deep divisions over his push for military action against the Syrian regime's alleged use of chemical weapons.

Obama cleared the first hurdle Wednesday in his race to win domestic congressional backing for punitive strikes but is also seeking broader international support.

Speaking during a trip to Stockholm he said the world had set "a red line" for Syria and it could not now remain silent in the face of the alleged chemical weapons attack on Damascus suburbs.

But Russian President Vladimir Putin, a fierce opponent of the proposed military action, warned on the eve of the summit he is hosting in Saint Petersburg that it would be unacceptable for the West to go ahead with military action against Damascus without UN Security Council approval.

The Kremlin demanded "convincing" proof that the regime of Bashar al-Assad was responsible for using chemical weapons against its own people.

According to US intelligence, more than 1,400 people living in rebel-held suburbs of Damascus were killed in the strike, which involved the use of the sarin nerve gas.

Beyond convincing Russia, Obama has a tough sell ahead elsewhere, with China -- another veto-wielding Security Council member state -- having already expressed its "grave concerns" over unilateral military strikes.

German Chancellor Angela Merkel has repeatedly ruled out her country's participation in any US-led military strike against Assad's regime, while the British parliament has also rejected the idea.

But Obama said in Sweden: "I didn't set a red line. The world set a red line," referring to international rules banning the use of chemical weapons, even in case of war.

"My credibility is not on the line," he said. "The international community's credibility is on the line and America and Congress's credibility is on the line."

The Syria conflict threatens to torpedo items on the G20 agenda -- such as an "action plan" for sustainable and balanced global growth -- even though it has not been formally pencilled in.

Emerging nations' appeal to developed nations to pursue an orderly exit from economic stimulus measures, thereby limiting damage to their markets, also risks being drowned out at the summit.

Syria is certain to be the top issue in the flurry of bilateral meetings between the leaders of the world's top 20 developed and emerging nations around the seaside Tsarist Konstantinovsky palace in Strelna on the Gulf of Finland seashore.

White House officials have said Obama will hold meetings on the sidelines of the G20 with French President Francois Hollande, the main foreign backer of a strike on Syria, as well as the leaders of China and Japan.

While no formal bilateral meeting is planned with Putin, a White House official suggested there would likely be some kind of dialogue. (AFP)
