Fighters with a Kurdish separatist militant group that has waged a decades-long insurgency in Turkey began laying down their weapons in a symbolic ceremony on Friday in northern Iraq, the first concrete step toward a promised disarmament as part of a peace process.

The disarmament process will start under tight security in Iraqi Kurdistan and is expected to take all summer.

SULAYMANIYAH, Iraq (Reuters) -Dozens of Kurdistan Workers Party (PKK) militants began handing over weapons in a ceremony in a cave in northern Iraq on Friday, officials said, marking a symbolic but significant step toward ending a decades-long insurgency against Turkey.
