The United States and Russia will support a United Nations Security Council resolution to identify the perpetrators of attacks using chlorine and other chemical agents in Syria, Secretary of State John Kerry said Thursday.
The agreement to back the resolution was reached Wednesday night in a one-on-one meeting here between Mr. Kerry and Sergey V. Lavrov, the Russian foreign minister.
Diplomats at the United Nations said a vote on the resolution was scheduled for Friday.
Although the Organization for the Prohibition of Chemical Weapons has the authority to determine whether chemical weapons have been used in Syria, the measure is intended to hold a specific organization or individuals to account.
According to a draft of the resolution, a joint investigative panel of the O.P.C.W. and the United Nations would be established to identify “individuals, entities, groups or governments who were perpetrators, organizers, sponsors or otherwise involved in the use of chemicals as weapons, including chlorine or any other toxic chemical” in Syria.
