The Russian ambassador to Ankara was shot in an attack at an art gallery in the Turkish capital on Monday and the Russian RIA news agency said he had died of his wounds.
The Anadolu news agency said the gunman had been "neutralized" soon after the attack, which appeared to mark one of the most serious spillovers of the Syria conflict in Turkey. Relations between Moscow and Ankara have long been fraught over the conflict, the two supporting opposing sides.
Ambassador Andrei Karlov made a speech at the opening of a photographic exhibition. Hurriyet newspaper said Turkish special forces had surrounded the building. NTV said three other people were wounded.
