Watch | Gunman shoots Russian envoy in Ankara

A Turkish policeman fatally shot Russia's ambassador to Turkey on Monday in front of a shocked gathering at a photo exhibit and then, pacing near the body of his victim, appeared to condemn Russia's military role in Syria, shouting: “Don't forget Aleppo! Don't forget Syria!” The leaders of Turkey and Russia said the attack in Ankara, the Turkish capital, was an attempt to disrupt efforts to repair ties between their countries, which have backed opposing sides in the Syrian civil war.
