Turkish President Tayyip Erdogan has issued a stark message to Russia, warning them not to "play with fire" in the wake of a dispute over the downing of a Russian warplane.
He said: "We very sincerely recommend to Russia not to play with
"We really attach a lot of importance to our relations with Russia... We don't want these relations to suffer harm in any way."
The warning came as Turkey made claims that Russia's criticism of the shooting down of the jet near the Syrian border on Monday, and the country's subsequent threats of economic sanctions, had been "unacceptable".
Russia's government has reportedly been drawing up measures including freezing some joint investment projects and restricting food imports from Turkey after what one politician branded as the "intentional murder of our soldiers".
