The prospects of finding a political solution to the Syria conflict are in danger unless the international community acts fast to pressure the regime, the head of the main Syrian opposition group said Saturday, after new air strikes on rebel-held areas of Aleppo.

"The regime is not really interested in a political solution and they are not really interested in hearing the cessation of the hostilities initiative," the head of the Syrian National Coalition Anas al-Abdeh told AFP in Istanbul.

"We think that unless the international community does something about that, the whole prospect for the political solution will be in danger," he added after a general assembly meeting of the main opposition umbrella grouping in the Turkish city.
