U.N. Security Council said to be nearing deal on Syria resolution

UNITED NATIONS (CNN) -- The 15 members of the U.N. Security Council are being called to a consultation regarding text for a resolution on Syria's chemical weapons disarmament.

"We shall introduce text to full SC tonight," Mark Lyall Grant, British ambassador to the United Nations, tweeted Thursday.

A Western diplomat told CNN the consultation, scheduled to happen at 8 p.m. ET, would likely address a draft text that has been mostly approved by the United States and Russia.

Earlier, two senior State Department officials told CNN that the two countries were getting close to a deal.

"This is a breakthrough arrived at through hard-fought diplomacy," said a senior State Department official.

"The Russians have agreed to support a strong, binding and enforceable resolution that unites the pressure and focus of the international community on the Syrian regime to ensure the elimination of Syria's chemical weapons," the official said.

Three basic premises have been settled, a U.N. diplomat said Wednesday.

Russia has basically agreed to the points, but "small issues" remain to be decided, the source said.

The deal could still fall apart.

According to the source, the three premises are: 1. Accountability for attacks on August 21; 2. Binding and enforceable language for measures against Syria in case of violations in the disarmament regime or the use of chemical weapons; 3. The council will remain seized of the matter, meaning that further discussion will be expedited.

The resolution would not authorize automatic use of force if Syria is said to be in violation, as was previously sought by the United States, the source said.
