UK has new Syria chemical evidence - David Cameron

The UK has fresh evidence of the use of chemical weapons in Damascus, David Cameron has told the BBC as he arrives in Russia for the G20 summit.

Mr Cameron added: "Britain will be leading the argument on humanitarian aid. Britain will be one of the leaders in bringing forward plans for a peace process for Syria. Britain will be leading the argument across the globe for continuing to respond strongly on chemical weapons."

He said: "I absolutely believe that, having set a red line on the further big use of chemical weapons, it would be wrong if America was to step back and, having set that red line, to do nothing. I think that would send an appalling signal to President Assad and also to dictators elsewhere."

The government of Syrian President Bashar al-Assad has denied involvement and said the rebels were responsible, but Mr Cameron said evidence of the Assad regime's use of chemical weapons was "growing all the time" and scientists at the UK's chemical warfare research laboratories were investigating the attacks on 21 August.
