Gaziantep bomber from the cell of Diyarbak?r, Suruç and Ankara attackers

The suicide bomber of the May 1 bomb-laden car attack that killed two police officers in the southeastern Gaziantep province was linked to the city's Islamic State of Iraq and the Levant (ISIL) cell, known recruiting militants that carried out suicide bomb attacks of Diyarbak?r, Suruç and Ankara in 2015, reports have said. 

As police identified the bomber as ?smail Güne?, details about the militant's allegiance and background began to emerge. Police reports showed that five days before the attack, Güne?'s name was mentioned in a letter about a possible attack in the city. Prepared using intelligence, the letter, which warned that "ISIL was conducting exploration work to stage an attack targeting the security, military and police units and critical public institutions in Gaziantep," was sent to officials with the names of suspects including ?smail Güne? and Yunus Durmaz.  

The letter also showed information that Durmaz carried out his exploration by "recording videos and taking pictures for the group and that he was ready to provide many suicide bombers."

The reports found that Güne? joined ISIL in 2014 when he crossed to Syria with his uncle, Ahmet Güne?.

Acting with a sub-group in Syria for a while, Güne? returned to Turkey and joined to the Durmaz group led by Yunus Durmaz - the mastermind of the Suruç and Ankara attacks. 

Upon his return to Turkey, Güne? was put under surveillance by counter-terror and intelligence units, who identified him as a "sponsor individual for the terrorist group ISIL." Güne?'s information and picture were also recorded by the units, as he was followed after Suruç and Ankara attacks as a "passive militant."
