Bashar al-Assad promises to surrender all Syria's chemical weapons He warned that his promise "doesn't mean it is a one-sided process." "It counts most of all on the US renouncing threats of force and adhering to the Russian plan," Assad said. When the US stops supplying weapons to terrorists and we see they are committed to stability in the region, then we will be ready to see this process through to the end. He even linked the US to the deadly sarin attack on August 21 in a Damascus suburb which raised the spectre of US air strikes. If we look at the past few days, the [US] threats were not about giving up chemical weapons. They were based on a provocation [on August 21]... A provocation realised by the leadership of the United States. The Syrian president also warned that any attack on Syria would be disastrous for the Middle East. "I think any war with Syria could quickly turn into a war that would destroy the entire region and lead to decades of instability," he said. He denied bowing to US pressure, saying that he had agreed to the idea of chemical disarmament only because the Russians had proposed it. Syria's deputy prime minister also suggested yesterday that the Russian proposal would only succeed if the United States and its allies pledged not to attack Syria in the future. "We want a pledge that neither it [the US] nor anyone else will launch an aggression against Syria," said Qadri Jamil. A UN report into the chemical weapons attack will provide circumstantial evidence that indicates Mr Assad's government is culpable, Western officials said. Under the terms of the UN mandate, inspectors are only authorised to conclude whether chemical weapons have been used in Syria, without apportioning blame. However, the testing of soil, urine and blood samples from victims, as well as of ammunition collected from the area, have also reportedly supplied strong clues that point to the regime. "Only the regime had the [chemical weapons] stocks, the [firing] vectors and the interest in doing it, so we can draw a conclusion from that," Laurant Fabius, France's foreign minister, told French radio. Led by the Swedish scientist Ake Sellström, the inspectors travelled to Damascus last month to gather evidence from the site where the nerve agent was detonated. The findings by the UN team may indicate how the nerve agent was made and deployed, analysts have said, which in turn would help identify the perpetrator.
