A delegation from one of Turkey’s biggest pro-Kurdish political parties has met a leading figure of the Kurdish movement in prison, the latest step in a tentative process to end the country’s 40-year conflict. Three senior figures from the Peoples’ Equality and Democracy Party, or DEM, met Selahattin Demirtas at Edirne prison near the Greek border on Saturday. It comes two weeks after a DEM delegation met Abdullah Ocalan, the imprisoned head of the militant Kurdistan Workers’ Party, or PKK. Demirtas credited Ocalan with raising the chance that the PKK could lay down its arms.
