So the Russian ambassador to Turkey was murdered this evening in an 'assassination attempt' - that was allegedly carried out in retaliation for the crisis in Aleppo.
Before opening fire on Andrei Karlov the gunman reportedly shouted in Turkish: "We die in Aleppo, you die here", then continued shouting allahu akbar several times. At least three others were injured in the attack during the ambassador's speech at an art gallery in the Turkish capital Ankara.
Mr Karlov was rushed to hospital in a critical condition but died soon after.
The attacker, who is believed to be a police officer, fired a shot into the air as the ambassador spoke and then shot him. The video and more photos below...
