UN commission downplays claim Syria rebels used sarin

The UN Commission of Inquiry on Syria has sought to distance itself from comments made by one of its members that there was evidence of the nerve gas sarin being used by rebels.

Carla Del Ponte said testimony from victims and doctors had given rise to "strong, concrete suspicions but not yet incontrovertible proof".

The commission stressed that it had not reached any "conclusive findings".
