Kurdish rebels suggested on Friday, Jan 11 that clandestine Turkish nationalists may have assassinated three Kurdish activists in Paris, but Prime Minister Tayyip Erdogan said the killings appeared to have been the result of an internal feud, Reuters reported.

The Kurdistan Workers Party (PKK) said the execution-style killings in an institute in central Paris had been premeditated and planned and warned France would be held responsible if it failed to get to the bottom of their deaths.

Sakine Cansiz, a founding member of the PKK, and two fellow activists were found shot in the head early on Thursday in an attack which shocked the Kurdish community and overshadowed peace moves between Turkey and the rebels.

Turkey put its missions in Europe, home to a large Kurdish diaspora , on alert and asked the French authorities to boost security around its interests there, after the pro-Kurdish Peace and Democracy Party (BDP) called for protest meetings.
