Chaos and violence continues in Aleppo, which now appears to be the legacy that President Barack Obama will leave the world.
Now, a shooter who was apparently screaming about Aleppo, shot Andrey Karlov, the Russian ambassador to Ankara. He has held the post since 2013.
His death has been reported but unconfirmed.
This is what we know:
Three other people were reportedly hurt.
Further gunfire has been heard, according to CNN Turk, and the gunmen is reportedly still at large.
CNN Turk said there were reports that the assailant had entered the gallery with a police ID and had opened fire on the ambassador as he made a speech. A photo broadcast on TV showed two people lying on the ground in the gallery.
CBS News adds:
According to the Ministry of Foriegn Affairs, Karlov began his diplomatic career in 1976, and has previously served in South Korea. He became Russian Ambassador to Turkey in July of 2013.
Russia and Turkey recently negotiated a cease-fire in the Syrian civil war between rebels and the Assad regime fighting over the city of Aleppo.
Turkey has struggled with a series of deadly terrorist attacks recently, from both Kurdish rebels and groups like the Islamic State of Iraq and Syria (ISIS.)
Earlier this year, there was a diplomatic crisis between the two nations when Turkey shot down a Russian jet it said had violated their airspace during maneuvers over Syria.
