By Ako Rasheed SULAYMANIYAH, Iraq (Reuters) -Thirty Kurdistan Workers Party (PKK) militants burned their weapons at the mouth of a cave in northern Iraq on Friday, marking a symbolic but significant step toward ending a decades-long insurgency against Turkey.

A ceremony in northern Iraq on Friday saw a handful of Kurdistan Workers’ Party (PKK) militants lay down their weapons, a small but hugely symbolic gesture that marks the beginning of an end to a conflict with the Turkish state that’s lasted nearly five decades and cost tens of thousands of lives.

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