Huseyin Celik, the deputy chairman of Turkey’s ruling party, said the attack appeared to be the result of “an internal feud” within the PKK, but he did not provide any evidence to back his statement.

Mr. Celik also suggested the slayings were an attempt to derail the peace talks.

The PKK does have a history of internal executions. While many Kurdish activists and militants were victims of extra-judicial killings blamed on Turkish government forces in the 1990s, it’s not known whether they also targeted any exiled Kurds in Europe.

Gultan Kisanak, a joint leader of the Kurdish political Party, Peace and Democracy Party, called Ms. Cansiz “an idol of the Kurdish people and Kurdish women” and rejected the possibility of an internal feud within the PKK.

“She was a hero and true revolutionary who would not even waste a minute for the good of the Kurdish women,” she said.

“This is a trap placed on the path to a solution of the Kurdish problem, it is a political assassination,” Ms. Kisanak said.

“How dare they present the murder of a revolutionary on internal strife without any evidence?” she said in response to Mr. Celik’s comment.

In the streets of Paris, the protesters blamed Turkey.

“Where are French? Where is that solidarity? I think that the state of Turkey did this,” said one man in the Paris crowd, identifying himself only as Ali.

Turkey frequently accuses France, Germany and the Netherlands — home to large numbers of Kurds from Turkey — of supporting the PKK, failing to extradite wanted militants and not backing Turkey’s “fight against terrorism.”

Turkish officials say the PKK raises funds through extortion or other criminal activities in European countries that have a large number of Kurdish immigrants.

France has a large Kurdish community concentrated in the Paris region, and French police occasionally have arrested Kurds suspected of illegally financing the PKK.
