The White House has said they were “deeply sceptical” of claims by the Syrian government that chemical weapons were used by the Syrian opposition, in a rocket attack in Aleppo.
Sana news agency reported that,
"Terrorists launched a missile containing chemical products into the region of Khan al-Assal in the province of Aleppo, killing 15 people, mainly civilians".
However, Jay Carney, speaking on behalf of US President Obama, said,
“on that specific allegation we have no evidence to substantiate the charge that the opposition has used chemical weapons. We are deeply skeptical of a regime that has lost all credibility, and we would also warn the regime against making these kinds of charges as any kind of pretext or cover for its use of chemical weapons”.
Last year, President Obama warned of the use of chemical weapons in Syria, stating that it would be a “red line” for the US.
