Turkish media reports have said a new suspect has been arrested in connection with the 2016 assassination of Russia’s ambassador to Turkey.
Authorities arrested former police officer Ramazan Yucel in the capital, Ankara, after questioning him, reports said on December 13.
Russian Ambassador Andrei Karlov was shot dead while speaking at a photography exhibit in Ankara on December 19, 2016, by an attacker who shouted "Don't forget Aleppo" and other words that seemed to refer to Russia's involvement in the Syrian conflict.
Turkish authorities said Karlov's killer was Mevlut Mert Altintas, a 22-year-old policeman who was off duty at the time. Altinas was later shot dead by police at the scene.
In November, a former producer at the state-run TRT television channel, Hayreddin Aydinbas, was arrested in connection with the assassination.
Turkish officials have said they have arrested several other men suspected of involvement in the murder.
