ENNISKILLEN, Northern Ireland: Russia’s Vladimir Putin derailed Barack Obama’s efforts to win backing for the downfall of Syrian leader Bashar Assad at a G-8 summit Tuesday, warning the West that arms supplied to the rebels could be used for attacks on European soil.

 

After two days of intense talks that fell far short of what Obama and Prime Minister David Cameron had been hoping for, Putin fumed against Western moves to supply weapons to rebels while defending his own supplies of arms for Assad.

 

“We are supplying weapons under legal contracts to the legal government. That is the government of President Assad. And if we are going to sign such contracts, we are going to deliver,” the Russian president said.

 

Putin, isolated at the summit, repeatedly clashed with other leaders over the fate of Assad and resisted pressure to agree to anything that would imply Assad should step down. In the end, a G-8 communique did not even mention Assad’s name.

 

The summit in a secluded golf resort in Northern Ireland ended with G-8 leaders calling for peace talks to be held as soon as possible to resolve the Syrian civil war. This has broadly been their position for months.

 

No date was mentioned for a peace conference called by Moscow and Washington, which was supposed to take place next month but now appears to be on hold, after the United States announced last week that it would arm the rebels.

 

A source at the summit said the peace conference would now be put off at least until August.

 

A key stumbling block for the proposed talks is the role of Iran.

 

French President Francois Hollande said that Iranian President-elect Hassan Rouhani would be welcome at Syria peace talks “if he can be useful.”

 

Western nations including France have previously been firmly opposed to Iran taking part.

 

At the summit, Putin struck a defiant tone: He hinted that Obama had tried to isolate Russia, that other leaders were divided, and that plans to send arms to Syrian rebels could lead to murders such as that of a British soldier on a busy London street last month.

 

“British people have lately witnessed a tragedy, and we lived through it together, when right in the streets of London a British army serviceman was brutally murdered outside his barracks,” Putin said.

 

“Is it these people that the Europeans want to supply arms? What happens next with those weapons? Who will control in which hands they end up? They could possibly [end up] in Europe,” he added.

 

Obama and his allies want Assad to cede power while Putin believes that would be disastrous at a time when no clear transition plan exists.

 

In the final document, G-8 leaders called on the Syrian authorities and the opposition to commit to destroying all organizations affiliated with Al-Qaeda – a reflection of growing concern that Islamist militants were playing a more dominant role in the rebel ranks.

 

British Prime Minister David Cameron, who chaired the summit, said separately after the talks that the West believed strongly that there was no place for Assad in a future Syria.

 

“It is unthinkable that President Assad can play any part in the future of his country. He has blood on his hands,” Cameron told reporters.

 

Cameron said the main breakthrough was an agreement that a transitional government with executive powers was needed and a deal to call for an investigation into chemical weapons use.

 

Both, however, are old positions that have already been agreed. The West and Russia still disagree over whether Assad should be excluded from the transitional government, and over how to carry out chemical weapons investigations.

 

“We strongly endorse the decision to hold as soon as possible the Geneva conference on Syria,” the final communique read, without saying when the conference should be held.

 

For his part, Putin renewed criticism of U.S. plans to send weapons to Syrian rebels, which the Obama administration announced after concluding that Assad’s forces had used nerve gas.

 

Putin said other G-8 leaders had expressed doubts that Assad’s forces had used chemical weapons.

 

Looking mostly tense throughout the meeting, Putin had faced a barrage of criticism over his Syria stance. Canadian Prime Minister Stephen Harper accused him of supporting “thugs” in Damascus, while his meeting with Obama was frosty and both looked uncomfortable.
