The U.S. State Department said on Tuesday that the Russia-proposed UN draft resolution on Syria still needed amendment in order to be acceptable to Washington, Xinhua reported.
"You know, it's evident, obviously, that more work needs to be done, from what we've seen so far," State Department spokesman Mark Toner told reporters.
"We're going to work to realize a draft resolution that, you know, holds the Assad regime accountable, but also, obviously, supports the Arab League efforts in this regard," he said.
Toner admitted that the United States was pleased that "the Russians have shown a willingness to work with us on this," although the draft resolution was still not acceptable to Washington.
In October last year, Russia and China vetoed a Security Council draft resolution on Syria which was sponsored by some European countries. In December, Russia circulated at the UN its updated draft on the Syrian crisis.
Russian Foreign Ministry said on Tuesday that the country would not support a possible deployment of Arab League peacekeepers to Syria because the alliance lacks legal authority for such a move.
