Turkey releases recording of warnings to Russian warplane
Turkey has released audio recordings of what it says are the Turkish military's warnings to the crew of the Russian plane that was shot down at the border with Syria.
The recordings indicate that the plane was warned several times that it was approaching Turkey's air space and asked to change course.
A voice is heard saying: "This is Turkish Air Force speaking on guard. You are approaching Turkish air space. Change your heading south immediately."
Turkish fighter jets shot down the Russian Su-24 bomber on Tuesday, saying it violated Turkey's air space despite repeated warnings.
The plane's surviving pilot has denied that his jet veered into Turkish air space and rejected Turkey's claim that it issued repeated warnings to the crew.
Meanwhile, Russian media reported that Russia has already deployed long-range air defence missiles at its base in Syria.
Moscow announced the move on Wednesday, saying the missiles would help destroy any target that may threaten its warplanes there following the downing of the military jet.
The Ria Novosti news agency quoted its own reporter on the ground as saying that S-400 missiles were delivered on Thursday.
The S-400s are based in Syria's coastal province of Latakia, just 50 kilometres (30 miles) away from the border with Turkey and are capable of striking targets within a 400-kilometre (250-mile) range with deadly precision.
