Syria’s north-western province of Idlib is the last major area under rebel control. Over the course of the fighting it has become home to huge numbers of internally displaced people.
Around three million are now concentrated in this largely rural region. A series of deals have allowed rebel fighters from other areas to move there too, as the Syrian government has consolidated its hold over large swathes of the country.
Now President Bashar al-Assad is turning his attention towards Idlib.
