HATAY, Turkey — Tens of thousands of people gathered Thursday in the southern city of Diyarbakir to mourn the deaths of three Kurdish activists murdered in Paris last week, an outpouring that some said amounted to the largest political gathering that the Turkish authorities had ever allowed the Kurds to stage.

With fragile peace talks to end three decades of armed insurgency just beginning, top Turkish and Kurdish officials called for calm, and none of the national television networks carried the event live. But a few Web portals provided real-time coverage as crowds accompanying three funeral trucks for the women poured into Batikent Square in Diyarbakir, the hub of Kurdish political and cultural life. The most prominent of the slain women, Sakine Cansiz, was a founding member of the insurgent group, the Kurdistan Workers’ Party, or P.K.K. Experts said she had been raising funds for the group in Europe.

The private IMC TV portal showed that many in the crowd wore white scarves for peace and black clothing for mourning, as suggested by the pro-Kurdish Peace and Democracy Party, the organizer of the ceremony.
