Turkey criticises 'unfounded' Russian claims of IS oil purchases
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 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".
