ERBIL, IRAQ: The authorities in Iraqi Kurdistan have accused Turkish Kurdish rebels of the Kurdistan Workers Party (PKK) of ordering the July 17 murder of the Turkish vice-consul in regional capital Erbil.

The federal government in Baghdad has often blamed the PKK for carrying out attacks against Turkish targets from its rear bases in Iraq鈥檚 northern mountains but a statement issued late on Friday was a rare accusation against their fellow Kurds by the autonomous regional authorities. 

The PKK鈥檚 armed wing had denied responsibility for the assassination. But the Iraqi Kurdish authorities said that based on a detailed confession by the suspected Turkish Kurdish gunman, Mazloum Dag, 27, the murder was carried out on the orders of top PKK commanders.

Turkish Vice-Consul Osman Kose was gunned down with two Iraqis while they dined on a restaurant terrace in Erbil.

Iraqi Kurdish security services said that the murder had been three months in the planning by PKK commanders in their heavily forrtified hideouts in Iraq鈥檚 Qandil mountains.

They said they had arrested three Turkish and three Iraqi suspects.

Dag鈥檚 arrest last Saturday was immediately seized on by the Turkish media as his sister Dersim is a member of Parliament for Turkey鈥檚 main pro-Kurdish party, the People鈥檚 Democratic Party (HDP).

The HDP, the country鈥檚 second largest opposition group, is regularly accused by President Recep Tayyip Erdogan of links to the outlawed PKK.

The HDP 鈥渟trongly鈥� condemned the Erbil attack, calling it an 鈥渁bsolutely unacceptable provocation attempt.鈥�

In May, Turkey launched a major ground offensive and bombing campaign against the PKK in Qandil, the latest of many in the military鈥檚 three-and-a-half decade campaign against the rebels.

Analysts have suggested the attack on the Turkish diplomat might have been carried out in retaliation for the killing of several PKK commanders in the latest bombing campaign.

Following Kose鈥檚 murder, Turkey broadened its cross-border operations, launching airstrikes against PKK bases and members in the Kurdish-held Makhmur area south of Iraq鈥檚 second city Mosul.
