Turkey's Prime Minister has dismissed calls for an apology over the shooting of a Russian jet near the Syrian border, saying: "No country should ask us to apologise."
Ahmet Davutoglu was speaking after a meeting with Nato's general secretary in Brussels, during which the alliance reiterated its strong support for Turkey's right to defend its airspace.
Turkey says the jet made repeated incursions into Turkish territory and was warned multiple times before it was shot down. Russia disputes the claims.
Mr Davutoglu added that such incidents continued to be a risk as long as Russia and the US-led coalition against so-called Islamic State continued to carry out separate bombing campaigns.
Turkey has shown it is willing to take on Russia after downing a Russian fighter jet.
This incident will leave the American military profoundly alarmed that the Syrian conflict is now threatening to spiral out of all control.
