AYDIN, Turkey

Six people, who were arrested in the aftermath of the murder of the Russia’s envoy to Turkey, were released on Thursday, police sources said.

Altintas’s parents, sister, two uncles and aunt were released early in the morning in Turkey’s Aegean province of Aydin, said the sources who spoke on condition of anonymity due to restrictions speaking with the media.

Ambassador Andrey Karlov died on Monday after being shot multiple times at an art exhibition in Ankara. He was delivering a speech when the assailant, 22-year-old off-duty policeman Mevlut Mert Altintas, opened fire.

In total, 13 people were arrested including Altintas’s roommate in Ankara.
