A leading journalist in Istanbul has said the shooting of the Russian ambassador in Ankara "wasn't much of a surprise."
Andrey Karlov was shot by a young man, Mevlut Mert Altıntas, while giving a speech at an art gallery. Altıntas reportedly shouted "don't forget Aleppo" as he carried out the attack.
Karlov later died of his injuries in hospital, while his killer was "neutralised" by Turkish security forces.
Sara Monetta, the Deputy News Editor for TRT World, said anti-Russian sentiment has risen sharply in Russia as a result of Vladimir Putin's support for Syrian President Bashar al-Assad. Turkey has aligned itself with rebel factions in Syria's ongoing civil war.
"I'd say that recently the anti-Russian sentiment in Turkey has risen a lot for two reasons," she told Paul Ross. "The first is there are about 2.8 resident refugees in Turkey, a big chunk of the population.
"The second is that Russia is leading a war not only against Daesh [Isis] as they're claiming, but also against the opposition - which is supported by Turkey.
"So over the last few weeks, we've seen a number of demonstrations in Ankara, in Gazientep [on the Syrian border], to the point where security has been heightened around embassies and the consulates."
She said that the young gunman, Mevlut Mert Altıntas, "took advantage" of the "relaxed" event in order to carry out his attack.
