Russia and China have vetoed a United Nations resolution that would have placed sanctions on Syria in response to alleged chemical weapons attacks.
The measure, backed by the Western powers of Britain, France and the United States, would have imposed sanctions on 21 Syrians, organizations and companies that were allegedly involved in chemical attacks in 2014 and 2015.
The resolution would have also banned all countries from supplying the Syrian government with helicopters, which were used in the attacks.
The measure was drafted after a joint investigation by the U.N. and a global chemical weapons watchdog determined the Syrian government carried out at least three attacks involving chlorine gas. The groups also found that the Islamic State extremist group was behind at least one attack involving the use of mustard gas.
