A draft U.N. resolution obtained by The Associated Press would impose sanctions on 11 Syrians and 10 Syrian organizations and companies allegedly involved in chemical weapons attacks in the war-ravaged country.
The proposed Security Council resolution would also ban all countries from supplying Syria's government with helicopters, which investigators have determined were used in chemical attacks.
The resolution obtained by the AP Tuesday follows an investigation by the United Nations and the chemical weapons watchdog that determined the Syrian government was behind at least three attacks involving chlorine gas and the Islamic State group was responsible for at least one involving mustard gas.
The U.S., Britain and France have been pressing for sanctions on Syria. But Russia, Syria's closest ally, has questioned the investigators' conclusions linking attacks to the government.
