Fighters with a Kurdish separatist militant group that has waged a decades-long insurgency in Turkey have begun laying down their weapons.

SULAYMANIYAH, Iraq, July 11 (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.

The disarmament of the P.K.K., a group that has battled since the 1980s for Kurdish independence, could end a conflict that has killed more than 40,000 people.
