[BBC] – A gunman has shot dead Russia’s ambassador to Turkey, Andrei Karlov, apparently in protest at Russia’s involvement in the Syrian conflict.

Several other people were reportedly also injured in the attack, a day after protests in Turkey over Russian support for Syrian President Bashar al-Assad. The killer, said to be an off-duty Turkish policeman, opened fire at point blank range as Mr Karlov made a speech.

Police later “neutralised” the attacker, Turkish media say. Mr Karlov was rushed to hospital, reports said, but his death was later confirmed by the Russian foreign ministry.

Turkish President Recep Tayyip Erdogan has spoken to Russian President Vladimir Putin by phone about the attack, Mr Erdogan’s office said. Speaking outside the hospital where Mr Karlov was taken, Ankara’s Mayor, Melih Gokcek, said the killing was intended to ruin his country’s relations with Russia.

The attack was swiftly condemned by other countries:

• US state department spokesman John Kirby: “We condemn this act of violence, whatever its source. Our thoughts and prayers are with him and his family”
• UK Foreign Secretary Boris Johnson: “Shocked to hear of despicable murder of Russia’s Ambassador to Turkey. My thoughts are with his family. I condemn this cowardly attack”
• German Interior minister Thomas de Maiziere said his country stood with Turkey in a common fight against terrorism
• French President Francois Hollande “strongly” condemned the killing

While there were protests in recent days about the situation in Aleppo, on a political level the Turkish and Russian governments have been co-operating in the ceasefire operation, the BBC’s Turkey correspondent, Mark Lowen, reports.

Before the attack happened, a meeting of the Russian, Turkish and Iranian foreign ministers had been planned in Moscow for Tuesday. But tonight it seems the political fight over Syria’s future has spilled over into public hatred, our correspondent says.

Eight shots

According to Russian TV, the ambassador had been attending a photo exhibition called “Russia as seen by Turks”.

Video of the event shows Mr Karlov making a speech when gunshots ring out. Eight bullets are said to have been fired. The camera pulls back to show a smartly dressed gunman, wearing a suit and tie, waving a pistol and shouting.

He can be heard yelling “Don’t forget about Aleppo, don’t forget about Syria” and uses the Arabic phrase “Allahu Akbar” (God is great). Andrei Karlov, 62, was a veteran diplomat who had served as Soviet ambassador to North Korea for much of the 1980s.

After the fall of the USSR in 1991, he had a posting as Russian ambassador to South Korea before returning to the North for five years in 2001.

Taking up the Ankara posting in July 2013, he had to grapple with a major diplomatic crisis last year when a Turkish plane shot down a Russian jet close to the Syrian border.

Demanding a Turkish apology, Moscow imposed damaging sanctions – notably a freeze on charter flights by Russian tourists – and the two countries only recently mended ties.

Condemning the attack as an act of “terrorism”, Russian foreign ministry spokeswoman Maria Zakharova said Turkey had given assurances that there would be a comprehensive investigation, and those responsible would be punished.

“The memory of this outstanding Russian diplomat, a man who did so much to counter terrorism… will remain in our hearts forever,” Ms Zakharova said.
