Turkish troops have crossed the border into Idlib province, in a move Ankara says it is to enforce a de-escalation zone.

About 100 Turkish soldiers have moved into Syria's Idlib province in a convoy of armoured vehicles.

Ankara says it is to enforce a de-escalation zone in the war-torn country as part of a deal with Iran and Russia.

But there are suspicions Turkey's real motive is to stop the Kurds extending their territory in the region.

And there is also the matter of a group with former ties to al-Qaeda - Hay'et Tahrir al-Sham - which controls much of Idlib and is vowing to fight to the death.

What does Turkey's involvement mean for the war in Syria and can it help bring unity?
