A Gülenist Terror Group (FETÖ)-linked journalist on Tuesday implied PKK terrorists were set to kill the newly-appointed mayor of Diyarbakır, Cumali Atilla in a controversial tweet.

Bülent Keneş, the former editor-in-chief and columnist at English-language daily Today's Zaman, tweeted in the wake of the arrest of the former Diyarbakır mayor, saying: "May Cumali Atilla, who was appointed instead of Hasan Ölçer as the new administrator, rest in peace. My condolences for his loved ones, the PKK terror group does not forgive."

Hasan Ölçer is a lawyer who was appointed as a trustee to FETÖ-linked Koza İpek Holding, which is accused of financially supporting and disseminating propaganda for the terror group.

On Tuesday, a district governor was appointed to the post of Diyarbakır Metropolitan mayor in Turkey's southeast after the previously elected mayor Gültan Kışanak, a member of the pro-PKK Democratic Regions Party (DBP), was arrested last week on terror support charges.

Kışanak was detained Tuesday on charges of various crimes,including 'being a member of an armed terrorist group, making comments in support of a terrorist group, making calls for autonomy for Kurdish people, legitimizing violence and attending the funerals of terrorists'.

In September, an official report by the Justice Ministry revealed at full length the involvement of DBP municipalities in various crimes, including the Diyarbakır local branch of the HDP. The provincial branch of the HDP, the DBP, has participated in nationwide parliamentary elections twice since the party was formed.

Several district municipalities in Diyarbakır province were found guilty of constitutional crimes in 2015; namely, the districts of Sur, Silvan and Lice, for denying state authority and declaring self-governance. Municipal workers in the province also attended demonstrations in support of these so-called demonstrations for self-governance.

Vehicles belonging to many DBP municipalities, including those in Diyarbakır, used to carry and bury deceased terrorist members of the PKK and the PKK's Syrian offshoot the Democratic Union Party's (PYD) armed wing the People's Protection Units (YPG).

Evidence also revealed that some Diyarbakır municipal funds were wired to PKK terrorists while the municipality also collected a large sum of money from the public under the auspices of "charity for Kobani."

Diyarbakır Municipality vehicles were used to dig ditches during street clashes between the PKK and security forces, which began after the PKK ended a two-year-long ceasefire period by killing two police officers in their home in July 2015.

Prior to the coup attempt, the two terror groups are said to have collaborated. The FETÖ and PKK were equally guilty during the Oct. 6-7 events in 2014 that resulted in the deaths of dozens of civilians.

According to a report published in the Sabah daily, the PKK and FETÖ joined forces in the Oct. 6-7 events that killed 53 people.

In addition, Food, Agriculture and Livestock Minister Faruk Çelik said early September that the two terror groups are actually working toward a chaotic Turkey. "The PKK and FETÖ are making efforts together to create insecurity in southeast Turkey, but neither our people nor our security forces will give them a chance. We will save the region from this environment, which the local community is tired of," he said.
