Officials from Russia and Turkey have both said they will continue working to repair their already fractured relationship following the Monday assassination of the Russian ambassador to Turkey in Ankara. Ambassador Andrei Karlov was killed by a 22-year-old Turkish policeman, authorities have said. Afterward, the gunman shouted slogans about the besieged Syrian city of Aleppo and pointed his weapon at those in the audience who were listening to Karlov’s speech, before he himself was shot and killed by police. Turkey and Russia are on opposing sides of the war in Syria, but otherwise police have not spoken about the officer’s motive. Foreign ministers from both nations attended a previously scheduled meeting in Moscow on Tuesday. Turkish Foreign Minister Mevlut Cavusoglu said the two nations would work together to determine who was behind the “heinous terror attack” against Karlov.
