WASHINGTON (AP) — President-elect Donald Trump is condemning the killing of Russia’s ambassador to Turkey.

In a written statement, Trump calls the killing of diplomat Andrei Karlov a “violation of all rules of civilized order” and says it must be “universally condemned.”

Trump is also extending his condolences to Karlov’s family and loved ones.

A Turkish policeman fatally shot Karlov in front of an audience at a photo exhibit in Ankara. The assailant, who was identified as Mevlut Mert Altintas, a member of Ankara’s riot police squad, was later killed in a shootout with police. Authorities said three other people were wounded in the attack.

Trump called Altintas a “radical Islamic terrorist.” The gunman reportedly shouted, “We are the descendants of those who supported the Prophet Muhammad, for jihad.”
