Russia's ambassador to Turkey, Andrei Karlov, was shot and killed by a Turkish policeman at an art gallery in an apparent revenge attack.
The shooter, later identified as 22-year-old Mevlut Mert Altintas -- as Fox News reports -- was wearing a black suit when he shot Karlov in the back. He yelled, "Don't forget Aleppo!" according to CNN. It was apparent revenge for the Russian bombing of Aleppo.
The Daily Beast reports Altintas got into the event by claiming to be Karlov's bodyguard. At the time, Karlov was giving a speech at the Ankara Center for Contemporary Art. Dozens of still and video cameras were there to capture his remarks.
The New York Times reports Turkish and Russian officials say the killing was intended to ruin Russia-Turkey ties. According to the Times, Russian President Vladimir Putin, said that the killing was a "provocation aimed at derailed Russia-Turkey ties and the peace process in Syria."
