Russia 'will not forget' Turkish downing of warplane: Putin

He added that always considered and will always consider treachery to be the ultimate and lowest act

Russian President Vladimir Putin today vowed never to forget Turkey's downing of one of Moscow's warplanes, as he lashed out once again at the leadership in Ankara over the incident.

"We will not forget this complicity with terrorists. We always considered and will always consider treachery to be the ultimate and lowest act. Let those in Turkey who shot our pilots in the back know this," Putin told lawmakers in his annual state of the nation address.
