Tensions mount as Turkey accuses Russia of 'cover up'

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.
