Russia’s ambassador to Turkey was assassinated at an art exhibition in Ankara on Monday. The gunman shouted, “Allah Akbar” and “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.”
“We are currently in contact with Turkish authorities, who are assuring us that a thorough, comprehensive investigation will be conducted,” foreign ministry spokeswoman Maria Zakharova said in remarks broadcast on Russian television. “Murderers will be punished. Terrorism won’t resist to fight it.”

 

 Here’s what we know right now:

• Karlov was giving a speech at the opening ceremony of a photo exhibit when an assailant opened fire.

• Images of the scene showed a body on the ground as a man with a pistol stood nearby. In a caption, The Associated Press news agency described the man with the gun as the attacker. CNN has not independently confirmed the identities of the people in the photograph.

• In a video circulating on social media that shows the shooting, the gunman is heard shouting, “Allahu akbar (God is great). Do not forget Aleppo! Do not forget Syria! Do not forget Aleppo! Do not forget Syria!”

“Get back! Get back!” the man can be heard shouting in Turkish as he waves a gun.

“Only death will remove me from here. Everyone who has taken part in this oppression will one by one pay for it,” he said.

• Authorities haven’t said who they believe was responsible for the attack.
