An Ankara prosecutor's office has launched an investigation into the alleged killer of three Kurdish women activists who were shot dead in Paris last month, the state-run Anatolia news agency reported Wednesday.
The office will probe whether 30-year-old Omer Guney, who was charged in France with the January 9 triple murder, has any connections in Turkey, according to Anatolia.
French authorities initially described Guney as an ethnic Kurd who had acted as an occasional driver for the most prominent victim, Sakine Cansiz, a co-founder of the outlawed Kurdistan Workers Party (PKK).
Turkish media reported that Guney had entered Turkey more than 10 times, indicating he had been to Ankara between August 22 and 30 last year before travelling back to Paris.
French police sources said Guney had told them he had been a member of the PKK for two years, fuelling suspicions the brutal murders had been the result of an internal feud in the organisation.
But that was denied by the outlawed PKK.
The killings came amid peace talks between Turkey's secret services and jailed PKK leader Abdullah Ocalan with an ultimate goal of disarming the rebels and ending three decades of conflict which have claimed 45,000 lives mostly Kurds.
Turkey has suggested the murders bore the hallmarks of an internal feud within the PKK between opponents and peace-talk supporters.
