Russian President Vladimir Putin made statements on the assassination of Russia’s ambassador to Turkey, Andrey Karlov, who was shot in the back by a Turkish special forces police officer posing as a bodyguard during an Islamic terror attack Monday.

“There can only be one answer to this: stepping up the fight against terrorism, and the bandits will feel this.” Putin said in a brief meeting that was broadcasted and translated on RT shortly after Ambassador Andrei Karlov was killed in the attack.

Putin called Karlov an “outstanding diplomat” and said he knew him personally. He called for a memorial to be made in his honor throughout this ongoing investigation.

Photographers captured the horrific footage of 22-year-old Mevlut Mert Altintas opening fire inside an Ankara art exhibit, killing Karlov and wounding at least three others as Altintas pledged allegiance to Mohammed and jihad in Arabic. Reports have stated that Altintas refused to walk through the metal detector yet was allowed to enter the building regardless.

Cameras were fixed on Karlov, who was giving a speech at the Ankara Center for Contemporary Art when a man wearing a black suit sporadically opened fire and fatally shot Karlov in the back. Video captured the attack and shows Karlov grimacing and falling to the ground as the terrorist, later identified as Altintas, went on to shout, “Allahu Akbar!” repeatedly, a phrase we unfortunately know too well.

*BIG UPDATE: A high ranking Russian diplomat, Petr Polshikov, just hours after the terrorist attack described above broke out, was found dead from gunshot wounds in his flat in Moscow. Local media claims his wife was home with him at the time of the shooting but has no apparent injuries. Polshikov was a senior figure in the Latin American department of the Russian foreign ministry. He had served previously at the Russian embassy in Bolivia. This investigation is ongoing and any further updates will be posted.
