A Kurdish militia group has claimed that it executed two Turkish policemen for aiding the Isis attacker behind Suruc blast.

"A punitive action was carried out... in revenge for the massacre in Suruc," the People's Defence Forces (HPG), the armed wing of Kurdistan Workers' Party (PKK), said in a statement, according to Kurdish daily Rudaw.

The policemen were found dead in their shared home located in Ceylanpinar near the border of Syria on Wednesday morning. The duo, whom the Turkish police personnel identified as Feyyaz Ucar and Okay Acar, were found dead with their legs and hands tied behind their back. Both were shot in the head and ballistic reports indicate that the assassins had used guns with silencers for the purported revenge execution.

They were assassinated around 6.00 am (local time) and their identity cards including service weapons were seized by HPG assassins, Al Jazeera reported citing the HPG.

HPG, which is designated as a terrorist group by Turkey, said that the attack was carried out by 'Apoist Suicide Squad,' referring to PKK's jailed leader Abdullah Ocalan by his nickname "Apo."

In the suicide attack in Suruc on 20 July, 32 student volunteers, mostly members of Federation of Socialist Youth Associations (SGDF) were killed and at least 100 were injured.

The attack, which is one of the deadliest in Turkey, is believed to have been carried out by Isis.
