The bodies of three Kurdish women who appeared to have died from gunshots to the head were found early on Thursday at the Kurdish Institute in Paris, a police source said.
An employee of the institute told French media that one of the women killed was Sakine Cansiz, a founding member of the Kurdistan Workers Party (PKK) militant group.
“There is no doubt this was politically motivated,” said Berivan Akyol, the employee.
Police launched a murder investigation after discovering the bodies, along with three shell casings, in a room of the institute in central Paris, the source said, adding that their nationality was Turkish.
The PKK, which is fighting for greater autonomy for Kurds, has waged a 28-year insurgency against the Turkish state in which more than 40,000 people have been killed.
The Turkish government has recently acknowledged holding talks with the organization’s jailed leader, Abdullah Ocalan.
They have agreed a framework for a peace plan, according to Turkish media reports.
