DIYARBAKIR, Turkey — Tens of thousands gathered Thursday for the funeral ceremony of three Kurdish activists who were shot dead in ­Paris in an attack many believe was an attempt to derail peace talks. Kurdish legislators, meanwhile, vowed to support peace efforts to end the decades-long conflict between Turkey and autonomy-seeking Kurdish rebels.

The three female activists, including Sakine Cansiz, a founding member of the outlawed Kurdistan Workers’ Party, or PKK, were slain last week at a time when Turkey is engaged in talks with the rebels’ jailed leader, Abdullah ­Ocalan, to persuade his group to disarm.
