Free Syrian Army Commander Says He is Prepared To Join Assad's Forces To Fight Al Qaeda-Linked Fighters

Believes the Islamic State of Iraq and al-Sham is "very dangerous for the future of Syria"

The spectre is looming of a second Syrian civil war with the head of the opposition's official forces declaring that he is prepared to join regime troops in the future to drive out al-Qa'ida-linked extremists who have taken over swathes of rebel-held territories.

General Salim Idris, the commander of the Free Syrian Army warned that in particular Isis (Islamic State of Iraq and al-Sham), with thousands of foreign fighters in its ranks, was "very dangerous for the future of Syria" and needs to be confronted before it becomes even more powerful.
