Russia has accused Turkey of shooting down its warplanes near the border with Syria in order to protect its oil trade with militants group Islamic State (IS).
Addressing at international talks on climate change in Paris, Russian President Vladimir Putin called the downing of the plane a “huge mistake”.
Turkey has denied any ties to the terror group and is part of a US-led coalition carrying out air strikes against IS.
The Turkish government has refused to apologise for the incident.
One Russian pilot was killed and the other rescued following the crash on 24 November. Turkey says the jet entered its air space – an accusation Russia denies.
