French police have detained two people for questioning in connection with the killings of three female Kurdish activists in Paris last week, a judicial source said on Friday.

The two were arrested during the day on Thursday, the source said, the same day thousands of Kurds gathered in Turkey's southeastern city of Diyarbakir for the funerals of the three activists.

The source provided no details on the reasons the two people were detained or what role, if any, they are suspected of having played in the killings.

The three women, one of them 55-year-old Sakine Cansiz, a co-founder of the outlawed Kurdistan Workers' Party (PKK), were found shot execution-style at a Kurdish centre in Paris on January 10.

Turkish Prime Minister Recep Tayyip Erdogan has speculated the killings could be the result of an "internal feud" within the PKK aimed at sabotaging the talks
