Turkish police detained six people over the killing of the Russian ambassador, state media said on Tuesday, widening a probe to relatives of the off-duty policeman who shouted «Don’t forget Aleppo!» as he gunned the envoy down.
With the Turkish capital already on high alert after a string of attacks this year, an individual also fired outside the US embassy in Ankara overnight in a separate incident.
President Vladimir Putin declared «we have to know who directed the hand of the killer» and the Kremlin said a Russian investigative team were flying to Turkey to probe the murder.
An unprecedented three-way meeting between the foreign ministers of Turkey, Russia and Iran in Moscow over the Syria crisis was meanwhile set to go ahead despite the killing.
Ambassador Andrei Karlov was shot four times in the back by Turkish policeman Mevlut Mert Altintas, 22, as he opened an exhibition of Russian photography in Ankara.
Turkey identified the killer as 22-year-old Mevlut Mert Altintas, who had worked for the Ankara riot police for 2-1/2 years. Altintas, who also shouted slogans associated with Islamist militancy after shooting ambassador Andrey Karlov, was killed minutes later by members of Turkey’s special forces.
