The Turkish military has released an audio recording of what it described as warnings to a Russian warplane before it was shot down on the Syrian border.
In the recording, a voice speaking in English said “change your heading south immediately”.
Turkey also said that it had tried to rescue the SU-24 bomber’s two pilots. One of them was killed by gunfire as he parachuted from the burning plane.
The other pilot was rescued. He denied claims that the jet had violated Turkish airspace and warnings had been given.
The plane crashed into a mountainside on Syrian soil after being hit by a missile from a Turkish F16 fighter jet on Tuesday.
Tensions have escalated between the two countries over the incident, with Russian President, Vladimir Putin, describing it as a “stab in the back” and warning of “serious consequences”.
NATO has disputed the claim by the Russian government that one of its planes entered into Turkish airspace by mistake.
According to NATO Secretary-General, Jens Stoltenberg, Russia’s reason was not explanatory enough for the violation of Turkish airspace.
The Russian government had explained that the incident was due to bad weather, stating that its plane did not know when it entered into turkey, claiming it was an honest mistake.
Russia has been conducting airstrikes in Syria, claiming to be targeted at the Islamic State militants there.
Rights groups have denied this, noting that the strikes were targeted at the opposition rebel groups in Syria, thereby helping the government of President Bashar Al-Assad.
The US and other western countries are also suspecting that Russia is indeed helping the Syrian government and have called for an end to the airstrikes.
