The investigation into the assassination is being led by Turkey. Russia has formed a group of investigators to help Turkey in its effort. The Russian team is set to arrive in Ankara on Tuesday, Russian Foreign Minister Sergey Lavrov said. Russia considers the killing of its ambassador a terrorist attack, possibly aimed at derailing its relations with Turkey.

Karlov is the fourth Russian ambassador to have been killed in office in the long history of the country. Aleksandr Griboyedov was killed in 1829 in Persia, after a mob stormed the Russian embassy seeking to lynch three Armenians, who had been granted refuge there.

Vatslav Vorovsky fell victim to a political assassination in 1923 during a mission in Lausanne, Switzerland. Pyotr Voykov died in 1927 in Poland at the hands of Russian monarchist conspirators.
