An aircraft in service with Russia's air forces has been shot down by Turkey in the air near the border with Syria, local media report citing military sources.

Turkey's Presidency has confirmed the plane was Russian, after initial suggestions it might have been in service with the Syrian air forces.

The incident occurred north of the Syrian port of Latakia. Reportedly, Turkish authorities had issued ten warnings in less than 5 minutes against possible violations of the country's airspace.

The fate of the two pilots is not clear, with unverified footage showing one of them has been killed. Earlier reports suggested they were captured by Syrian Turkmen.

H?rriyet Daily News quoted PM Ahmet Davutoglu's office as saying Ankara is to consult with NATO and the United Nations on the latest developments.

According to information available so far the Su-24 was gunned down from the ground while flying at an altitude of 6000 meters.

It was difficult to immediately confirm whether the downed Su-24 was part of Syria's or Russia's air forces.

Ankara suggests the aircraft had entered into Turkey's airspace.

But Russia's Defense Ministry, quoted by Sputniknews, says it had not breached the airspace of Turkey.
