SULAYMANIYAH, Iraq (AP) — Fighters with a Kurdish separatist militant group that has waged a decades-long insurgency in Turkey have begun laying down their weapons. About 30 fighters took part in a symbolic ceremony Friday in northern Iraq. The move was the first concrete step toward a promised disarmament as part of a peace process. The Kurdistan Workers’ Party, or PKK, announced in May it would disband and renounce armed conflict to end four decades of hostilities. The move came after PKK leader Abdullah Öcalan urged his group in February to convene a congress and formally disband and disarm. Öcalan has been imprisoned on an island near Istanbul since 1999.
