The PKK's executives have reportedly fled into northern Syria, controlled by Saleh Muslim's Democratic Union Party after Turkey's retaliatory strikes dealt a heavy blow to the separatist group's bases in northern Iraq.
Intelligence sources said that PKK leaders started heading to the PYD-held areas, or Rojava, along with their armed supporters in order to spend winter in a safe area.
It is claimed that the decision to move into Rojava was made when PKK's heavyweight in Qandil, Cemil Bayık, huddled with senior officials from Syria's main Kurdish party, PYD, last August.
The move was a direct result of Turkey's reprisal attacks which destroyed the terrorist bases, leaving them unfit for use, it has reported.
Ferman Hüseyin, dubbed Bahoz Erdal, and Duran Kalkan are among the PKK executives, who were seeking a shelter in Syria's predominantly Kurdish region.
PKK terrorists were said to have moved into crowded civilian settlements in the towns of Kobani, Afrin and Resulayn on the border with Turkey.
According to intelligence sources, the strip stretching between Kobani and Resulayn will be controlled by Syrian Kurdish militant leader Bahoz Erdal, accused of orchestrating several terrorists attacks in Turkey between 2010 and 2012. Duran Kalkan, also known as Selahaddin Abbas, will be in charge of controlling the strip between Resulayn.
Intelligence sources warned that the outlawed organization had stored a number of weapons and ammunitions in some storage facilities into these regions.
