Envoys from all 28 Nato countries are to hold a emergency meeting to discuss Turkey’s campaign against the Islamic State group and Kurdish militants.
The meeting in Brussels was called by Turkey, which has become involved in the Syrian conflict in recent days.
The country, which had previously been reluctant to intervene, has launched raids against IS in Syria and Kurdish PKK guerrillas in northern Iraq.
The strikes followed a wave of attacks by militants on Turkish soil.
Turkey, a key Nato member, called today’s meeting of the North Atlantic Council under Article 4 of the alliance’s founding treaty.
