Turkey's prime minister has called on France to immediately shed light on the slayings of three Kurdish rebel activists in Paris.

Recep Tayyip Erdogan on Saturday also criticized French President Francois Hollande — who has said he knew one of the women — saying he should explain "to the world" why he had met with "terrorists" wanted by Turkey.

The three, including the founding member of the autonomy-seeking Kurdish rebel group, the PKK, were found shot dead on Thursday at a time when their jailed leader is holding peace talks with Turkey.

Turkey and its allies have labeled the group a terrorist organization. But Turkey frequently accuses France and other European nations of failing to cooperate against the rebel group.
