The UN has adopted a resolution aimed at identifying those behind chemical weapons attacks in Syria.

UN chief Ban Ki-moon and the head of the Organisation for the Prohibition of Chemical Weapons (OPCW) will be asked to prepare a plan for an inquiry.

The vote came after the US and Russia agreed on the final text of the resolution.

A mission to eliminate Syria’s chemical arsenal was set up after a deadly attack outside Damascus in August 2013.

Late last year, the OPCW declared it had removed or destroyed all 1,180 tonnes of declared toxic agents and precursor chemicals.
