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.

Several media outlets reported a gunfight later ensued after Karlov was shot.

Local broadcaster NTV television said at least three people were wounded and were taken to the hospital.

Mayor Gokcek told reporters outside the exhibition center 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.

"On behalf of my country and my people I once again extend my condolences to Russian President Vladimir Putin and the friendly Russian people," said Erdogan.
Putin promised a response to the assassination.

"The crime that has been committed is undoubtedly a provocation aimed at derailing the ties between Russia and Turkey, as well as the peace process in Syria," said Putin from Moscow.

"There is only one possible response to this - the strengthening of the fight against terror, and the bandits will feel it themselves."

Relations between Russia and Turkey were badly strained by the downing of a Russian warplane at the Syrian border in November 2015, but Turkey's apology earlier this year helped overcome the rift.

Russia and Turkey have co-sponsored the evacuation of civilians and opposition forces from Aleppo and discussed the prospect of organizing a new round of peace talks in Kazakhstan's capital, Astana.

'Don't forget Aleppo'

The assailant referenced the situation in Aleppo after he shot the ambassador in the back.

"Don't forget Aleppo, don't forget Syria," the attacker said in Turkish after gunning down the ambassador, as seen on a video shared by Turkish media from the scene.

"Whoever took part in this cruelty will pay the price, one by one... Only death will take me from here," the man said while holding a pistol.

Diego Cupolo, a photojournalist in Ankara, told Al Jazeera there were about 100 armed soldiers in camouflage and police officers at the scene, along with armored fighting vehicles.
The attack came a day before a meeting of Russian, Turkish and Iranian foreign and defense ministers in Moscow to discuss Syria.

Those talks will go ahead on Tuesday despite the murder of Karlov, the Interfax news agency said, citing Leonid Slutsky, a senior parliamentarian.

The Russian ambassador to Turkey was a career diplomat.

Karlov joined the diplomatic service in 1976. He served as Russia's ambassador to Pyongyang in 2001-2006, and later worked as the chief of the foreign ministry's consular department.
He had served as the ambassador to Turkey since 2013.
