Turkey releases audio of 'warning' to downed Russia jet
The Turkish military has released an audio recording of what it says were warnings to a Russian warplane before it was shot down on the Syrian border.
"Change your heading south immediately," a voice apparently says in English. Turkey said 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 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 F-16 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".

Moscow later broke off military contacts with Ankara and said it would deploy its most advanced anti-aircraft missile system in Syria to destroy any target that may threaten its warplanes.
It also said fighter jets would now escort its bombers during air strikes over Syria. On Thursday, Russia said it would impose stricter controls on food and agriculture imports from Turkey.
The US, the EU and the UN have all appealed for calm.
French President Francois Hollande is travelling to Moscow on Thursday to shore up support for action against the so-called Islamic State (IS) group, which killed 130 people in attacks in Paris earlier this month.
Pilot's story
The Turkish military said it had given 10 warnings to the Russian plane before it was shot down in Turkish airspace.
Russia said the pilot was rescued from rebel-held territory in north-eastern Syria in a 12-hour operation involving Russian and Syrian special forces.
A Russian marine was killed and a helicopter destroyed by rebels during the operation.
Syrian rebels released a video apparently showing the dead body of the second pilot, who was identified by Russia as Lt Col Oleg Peshkov.
Capt Murakhtin was speaking from the Hmeymim airbase, where Russia's aircraft are based.
Russia has been carrying out air strikes against opponents of President Bashar al-Assad since late September.
Turkish President Recep Tayyip Erdogan has defended the action by the country's military, saying "everyone must respect the right of Turkey to protect its borders".
He said he did not want to escalate tensions further.
Turkey is a member of Nato. The alliance has backed Turkey's version of events, although it, too, is calling for "diplomacy and de-escalation" to resolve the situation.
Russia and Turkey have found themselves on opposing sides in Syria's conflict, with Russia supporting President Assad, while Turkey is a staunch critic.
Turkey is part of the US-led coalition against Islamic State.
