"It is not a matter of operation, but a matter of timing. Qandil is no longer a faraway goal for us," Soylu stated.
The main base of the PKK, designated as a terrorist organization in Turkey, is reportedly located in the Qandil Mountains, an Iraqi mountainous area near the Iranian border.
Last January Turkey and the Free Syrian Army (FSA) opposition forces launched Operation Olive Branch in the Syrian northern district of Afrin aimed at "clearing" Turkey's Syrian border of the YPG and the Kurdish Democratic Union Party (PYD).
Tensions between Ankara and the Kurds escalated in July 2015 when a ceasefire between Turkey and the PKK collapsed over a series of terror attacks allegedly committed by the PKK members. The Turkish forces are involved in anti-PKK raids across the country.
