Nato has said it is closely following developments surrounding the loss of the Russian SU-24.

With fears of a diplomatic crisis growing Turkey, a Nato member, has said it will raise the issue within the alliance at the United Nations.

"Necessary initiatives will be taken at Nato, the UN, and at the level of countries concerned by the foreign minister upon instructions from Mr Prime Ministers, said the office of Ahmet Davutoglu, the prime minister, in a statement.

In October the North Atlantic Council, Nato's governing body, warned Russia that was courting "extreme danger" by sending planes into Turkish airspace.
