Turkey’s offensive against Islamic State (IS) militants and Kurdish groups intensified Monday following reports that its tanks shelled Kurdish positions inside Syria.

Here is a recap of key events in the area since a suicide attack killed 32 people in southern Turkey a week ago.

– July 20: The Syrian conflict spreads into neighbouring Turkey when an attack in the mainly Kurdish town of Suruc kills 32 people and wounds 100 others.

The blast targets pro-Kurdish activists just across the border from Kobane, Syria, the scene of fierce clashes between Kurdish fighters and jihadists last year.

– Turkish President Recep Tayyip Erdogan speaks of an “act of terror” and Prime Minister Ahmet Davutoglu adds: “Preliminary findings point to it being a suicide attack carried out by Daesh,” an Arabic acronym for IS.

– Protests erupt in major Turkish cities against Ankara’s alleged complicity with IS.
