PARIS (AP) — French prosecutors have filed preliminary murder and terrorism charges against a Turkish citizen who worked as a driver for one of three Kurdish activists who were gunned down this month in Paris, an official said Monday.

The suspect, identified as Omer Guney, 30, drove for the most prominent victim, Sakine Cansiz, a woman in her 50s who helped found the Kurdistan Workers Party, or PKK, a rebel group seeking autonomy for Turkey’s Kurds. Guney has told investigators he has been a member of the PKK for two years, Prosecutor Francois Molins told reporters.
