SAINT PETERSBURG - World leaders at the G20 summit on Friday failed to bridge their bitter divisions over US plans for military action against the Syrian regime, as Washington slammed Moscow for holding the UN Security Council "hostage" over the crisis.
Despite not being on the original agenda of the summit hosted by Russian President Vladimir Putin outside Saint Petersburg, the leaders discussed the Syria crisis into the early hours of the morning over dinner amid the splendour of a former imperial palace.
Putin has emerged as one of the most implacable critics of military intervention against the regime of Syrian President Bashar al-Assad over an alleged chemical weapons attack on August 21, saying any such move without UN blessing would be an aggression.
There was no breakthrough at the dinner as leaders, including US President Barack Obama, presented their positions on the Syria crisis which only confirmed the extent of global divisions on the issue, participants said.
"The differences of opinions of the leaders were confirmed during the dinner," Kremlin spokesman Dmitry Peskov was quoted as saying by Russian news agencies.
"Some states were defending the view that rushed measures should be taken, overlooking legitimate international institutions. Other states appealed not to devalue international law and not to forget that only the UN Security Council has the right to decide on using force," he added.
A high-ranking source close to the talks said there was a disappointing lack of ambition at the dinner on the Syria issue, noting that Putin as host was keen not to aggravate tensions further.
But a French diplomatic source said the objective of the dinner "was an exchange between the top world leaders and not to come to an agreement".
The dinner went on into the small hours of the morning and even after a late-night opera show, Putin and British Prime Minister David Cameron had a meeting to discuss the Syria situation, the Kremlin said.
UN chief Ban Ki-moon Friday also warned that military strikes could spark further sectarian violence in the country which he said is suffering from a humanitarian crisis "unprecedented" in recent history.
"I must warn that ill-considered military action could cause serious and tragic consequences, and with an increased threat of further sectarian violence," Ban said.
The Syria crisis and prospect of military intervention has overshadowed the official agenda of the summit of leaders of the world's top economies and emerging markets to stimulate growth and battle tax avoidance.
