A Security Council diplomat says the United States and Russia have reached agreement on a draft United Nations resolution aimed at identifying the perpetrators of chemical weapons attacks in Syria so they can be brought to justice.

The diplomat, speaking on condition of anonymity because discussions were private, said Wednesday that the final draft has been circulated to all 15 Security Council members. They have until 10 a.m. EDT (1400 GMT) on Thursday to raise objections, the diplomat said.

The U.S. has been pressing for the council to take action to ensure accountability for an increasing number of alleged chlorine attacks. Russia's U.N. Ambassador Vitaly Churkin has said the council should look for the best way to ensure that people allegedly responsible for chlorine attacks are brought before a court.
