The PKK terrorist organization is run by a band of chieftains in the northern Iraqi mountains of Qandil. Qandil is a range of mountains 40 kilometers wide and 320 kilometers long with incredibly rough terrain situated in the northeast of Iraq, bordering Turkey and Iran. Its location is perfect for the PKK's leaders because they can easily avoid detection and Turkish air raids by frequently changing locations.
The PKK moved out of Turkey and Syria during the chaotic days of the first Gulf War and firmly entrenched itself in the Qandil mountains of northern Iraq. They have been there ever since.
