Russia's ambassador to Turkey assassinated in Ankara
A police officer assassinated Russia's ambassador to Turkey at an art exhibition in Ankara on Monday, officials said. The gunman shouted "Do not forget Aleppo!" as he opened fire.
The shooting of Ambassador Andrey Karlov was captured on video. Russia's foreign ministry described it as a "terror attack."
Russia has been instrumental in helping Syrian President Bashar al-Assad's regime in its push to retake the eastern sector of Aleppo, which had been held by rebels for nearly four years.
Here's what we know right now:
• Russian President Vladimir Putin called the assassination a "provocation," vowing to step up security at diplomatic missions. "This murder is clearly a provocation aimed at undermining the normalization of Russia-Turkish relations as well as at undermining the peace process in Syria promoted by Russia, Turkey, Iran and other countries interested in promoting settling the crisis in Syria," Putin said in televised remarks. "The only response we should offer to this murder is stepping up our fight against terror, and the criminals will feel the heat."
• Turkish President Recep Tayyip Erdogan said the killing won't dampen the two countries' efforts to build a stronger relationship. "We know that this is a provocation on destroying the relationship between Turkey and Russia during this normalization process. ... All the expectation of what they want to achieve with this attack will be in vain and never happen," Erdogan said in televised remarks Monday.
• Police officer Mevlut Mert Altintas was the gunman, Turkish Interior Minister Suleyman Soylu said in a press conference. The attacker was born in 1994 in the town of Soke in Turkey's Aydin province, he said. CNN initially reported the officer was was off-duty at the time of the shooting, but Turkish government statements left his duty status Monday unclear.
Revealed: The off-duty special forces officer, 22, who gunned down the Russian ambassador as Turkish police arrest his parents, sister and roommate
The assassin who gunned down Russia's ambassador to Turkey Andrey Karlov has been identified as a 22-year-old undercover police officer.
Mevlut Mert Altintas shot dead the ambassador at an event in Ankara before he was killed by special forces.
Altintas was filmed as he blasted the ambassador from behind with his semi-automatic handgun during the launch of a photographic expedition.
Before he was shot dead himself, Altintas shouted in Turkish: 'Don't forget Aleppo! Don't forget Syria!'
He then warned journalists filming the event: 'Stand back! Stand back! Only death will take me out of here. Anyone who has a role in this oppression will die one by one.'
Amid the chaotic scenes, eyewitnesses reported that Altintas shouted 'Allahu akbar', the Arabic phrase for 'God is great'.
Turkey's interior minister says that the gunman who assassinated Russia's ambassador to Turkey was a policeman.
Suleyman Soylu said that the gunman was working for the riot police squad in Ankara for the past two-and-a-half years.
He identified the attacker as Mevlut Mert Altintas, born in 1994.
Altintas’s father Esrafil, mother Hamidiye, and his sister, Seher Ozeroglu, who works in a clothes shop, were arrested in his hometown of Soke in Aydin, a province on western Turkey’s Aegean coast.
It is claimed he was active in his youth with President Erdogan's AKP party and may have been linked with the Al Nusra Front, an affiliate of Al Qaeda.
One witness said Altintas was dressed smartly in a black suit and tie and stood behind the ambassador as he made his speech.
The witness added: 'He took out his gun and shot the ambassador from behind. We saw him lying on the floor and then we ran out.'
