Syrians describe effects of alleged gas attack

16 May 2013 Last updated at 14:05 BST

A BBC news team has travelled to a town in northern Syria which eyewitnesses claim has been attacked with poisonous gas.

They entered Saraqeb and spoke to people who said they had suffered from chemical poisoning after two devices containing the gas were dropped from a helicopter last month.

The claims of an attack, which have not been independently verified, have been strongly denied by the Syrian government.

Ian Pannell and his cameraman Darren Conway report from Saraqeb.
