ISLAMIST rebels have reportedly overrun the last major government stronghold in a strategic Syrian province.

The capture of Jisr al-Shughour almost completes the coalition's control of Idlib, after they gained control of its main city last month.

Government troops have reportedly fled the area after days of intense clashes, although the claims could not be independently confirmed.

Qaeda affiliate Jabhat al-Nusra is leading the so-called Jaysh al Fateh (Army of Conquest) alliance of various factions, which does not include Isis.

Opposition television station Orient News aired images claiming to be from inside Jisr al-Shughour on Saturday, showing rebel fighters milling around the main square, raising their black flags.

A Twitter account affiliated with al-Nusra also posted photos claiming to be from the "liberated" city and other images showed what appeared to be bodies of government troops piled in the streets.
