Turkey has seen a wave of terrorist attacks in the last year, for which the government have mainly blamed Kurdish militants.
However, Isis are also widely suspected of having operated in the country.
Russian and Turkey have had a tense relationship in recent times, and both support rival factions in the Syrian conflict.
