Russia has been accused of trying to “cover up” its infringement of Turkish airspace with “unfounded” claims that Turkey is illegally importing oil from the so-called 'Islamic State' (IS) group in Syria.
Russian president Vladimir Putin claimed Turkey shot down its plane to protect what he described as profiteering from the oil trade – a charge Turkish prime minister Ahmet Davutoglu denies.
He told reporters: “It is not possible to cover up the violation of the Turkish airspace with unfounded accusations against Turkey.”
Mr Davutoglu renewed a call for Russia to keep military and diplomatic channels for dialogue open, insisting Russia’s stance was turning the Syria crisis into a “crisis between Russia and Turkey”.
