The UN has accused Isis and the Syrian government for using chemical weapons in Syria during 2014 and 2015, The Independent reports.
The Syrian government used chlorine gas in two attacks and Isis militants used mustard gas in one attack, the team from the United Nations and the world body's chemical weapons watchdog said.
Samantha Power, US ambassador to the UN, called the use of chemical weapons "a barbaric tool, repugnant to the conscience of mankind," and urged the Security Council to take "strong and swift action" against the perpetrators.
