U.S. Ambassador to the United Nations Samantha Power said Thursday that the key powers on the Security Council had reached an agreement on a resolution which would compel Syria to disarm its chemical arsenal.

"Agreement reached w/Russia on UNSC Resolution legally obligating #Syria to give up CW they used on their people," Power tweeted. She said that the resolution would go to the full Security Council this evening.

"The draft UNSCR establishes that #Syria's use of CW is threat to international peace & security & creates a new norm against the use of CW," she added in a second tweet.

According to reports, the language cites Chapter 7 of the U.N. Charter, which allows for military action to enforce Security Council resolutions.

A senior Russian official, however, said that the language would not include an automatic trigger compelling military action if Syria failed to comply, according to reports.

The resolution comes after the U.S. and Russia brokered a deal which would force Syrian President Bashar Assad turn over his chemical arsenal to international inspectors.

President Obama has pushed to disarm Assad after an Aug. 21 chemical weapons attack on civilians which the White House and western nations blamed on Damascus. Assad has waged a brutal civil war with opposition forces seeking his ouster.

Obama initially threatened U.S. military action against Assad, but dropped those plans in the face of congressional and public opposition.

Obama and Secretary of State John Kerry, though, have said that all options are still on the table to force Syria to comply with the chemical weapons deal.
