United Nations: The UN Security Council on Saturday unanimously authorized the deployment of up to 30 unarmed observers to Syria to monitor the country's fragile ceasefire.

Russia and China joined the other 13 council members and voted in favor of the Western-Arab draft resolution.

Russian UN Ambassador Vitaly Churkin, however, made clear that there were limits to the kind of UN action Moscow could support.

"Out of respect for the sovereignty of Syria we have cautioned against destructive attempts at external interference or imposing any kind of illusory fixes," he said.

Russia 'satisfied'

Earlier it was reported Russia would vote for a UN Security Council resolution on Saturday backing an international ceasefire monitoring force in Syria, Russia's UN ambassador said.

"Having reported to our capital, we are now satisfied" with the latest version of the resolution, ambassador Vitaly Churkin told reporters ahead of the vote at the UN headquarters.

Russia had strong reservations about the wording of the Western-drafted resolution during two days of intense negotiations on the resolution which will allow an advanced party of up to 30 unarmed monitors to go to Syria this week.

But a new version produced by the United States was sent to the other 14 members of the Council late Friday, which the Russian government approved.
