'Rebel atrocities strengthen Assad, turn Syrians off opposition' [Neil Clark © RT]

The Arab League has postponed Sunday's crisis meeting on Syria, where rebels are struggling to regain ground in the country's biggest city, Aleppo. Foreign ministers were to discuss a new envoy to Syria to replace Kofi Annan, who quit earlier this month.

UK-based journalist and broadcaster Neil Clark says fighting in Syria will only escalate, as the rebels get strong support from their western backers aimed at regime change.
