Russia's ambassador to Turkey was shot dead in front of a crowd at a posh art gallery in the capital Ankara as the angry gunmen screamed "don't forget Aleppo".
Police later killed the assailant on Monday night, Turkish station NTV reported.

Andrey Karlov, 62, was several minutes into a speech at an embassy-sponsored photo exhibition when a man who stood directly behind him in a dark suit shot the diplomat in the back from close range multiple times.

• Russia's foreign ministry spokeswoman Maria Zakharova made the announcement of Karlov's death in a live televised statement.
• The assailant was a 22-year-old off-duty police officer who worked in Turkey's capital, said Ankara's Mayor Melih Gokcek.
• After the initial shot, the attacker approached Karlov as he lay on the ground and shot him at least one more time at close range, according to an AP photographer at the scene.
• He also smashed several of the framed photos on exhibition, but later let the stunned guests out of the venue, according to local media.

Mayor Gokcek told reporters outside the exhibition centre the "heinous" attack was aimed at disrupting newly re-established relations between Turkey and Russia.

Presidents Vladimir Putin and Recep Tayyip Erdogan spoke by phone about Monday's attack.
