Opposition rebel groups in Syria have been trying to overthrow the President for the past eight years.
Now, Idlib could become the final battle between his forces and rebels.
The region is the last rebel-held stronghold, dominated by the armed group Hayaat Tahrir al Sham.
The government – with Russian help- launched a new offensive to retake Idlib last week.
Dozens of people have been killed in the past few days and tens of thousands more displaced.
Aid agencies have repeatedly warned that attacking Idlib could trigger the worst humanitarian crisis of the Syrian conflict.
Government forces are now making steady gains as they advance towards the town of Maarat al Numan
They want to capture the crucial M5 highway, which links the capital Damascus with Aleppo.
But do they stand a chance this time around?
And what will be the human cost?
