NATO has announced that the North Atlantic Council, the alliance's decision-making body, will be holding a Tuesday meeting after being called by Turkey invoking an Article 4 request, meaning the country believes its territorial integrity is under threat.

It is unclear from official statements on the matter so far if the meeting is strictly related to the fighting between Turkish forces and ISIS along the border, or if the recent spate of Turkish strikes against the Kurdish PKK in Iraq is also part of the meeting.

ISIS carried out a bombing in southern Turkey, near the Kurdish city of Kobani, killing 32 people last week. Since then, Turkish troops have fought ISIS along the border and carried out airstrikes against ISIS targets in northern Syria. At the same time, Turkey began attacking PKK targets in northern Iraq on Friday, and are accusing the PKK of being behind a bombing that killed two Turkish soldiers Sunday.
