NATO Secretary General Anders Fogh Rasmussen and Turkish Foreign Minister Ahmet Davutoglu have agreed to convene an urgent meeting of NATO members after a mortar bomb fired from Syria hit a Turkish border town, killing a woman and four children.
A NATO official told Reuters that its ambassadors will meet under NATO Article 4, which is used "when a member state feels it territorial integrity is under threat".
The meeting is due to take place tonight.
