Kurdistan Workers Party (PKK) fighters stand at formation in northern Iraq May 14, 2013. The first group of Kurdish militants to withdraw from Turkey under a peace process entered northern Iraq on Tuesday, and were greeted by comrades from the Kurdistan Workers Party (PKK), in a symbolic step towards ending a three-decades-old insurgency. The 13 men and women, carrying guns and with rucksacks on their backs, arrived in the area of Heror, near Metina mountain on the Turkish-Iraqi border, a Reuters witness said.
