Authorities have found two things common in suicide bombers involved in recent attacks: All are natives of Adiyaman province in southern Turkey and they are associated with Dokumacilar Unit of ISIS.
Dokumaci is the last name of their recruiter, Mustafa Dokumaci. In Turkish, Dokumaci means "weaver."
A woman whose son joined ISIS and went missing, held Dokumacilar member Seyh Abdurrahman Alagoz, perpetrator of the Suruc bombing in July responsible.
There were reports earlier about the existence of a group called the Adiyamanists, but in the last attack, in Ankara, they were firmly identified as Dokumacilar.
"Abdurrahman took my son away. I asked him where my son was. He said he was hurting too because his brother had joined ISIS also. Another young man and Seyh Abdurrahman seduced my son. My son, who was classmates with Seyh Abdurrahman, in turn deceived one of our relatives to join them. I told Seyh he was responsible for the fate of my son."
The woman, who wished not to be named, testified to a team from the Republican People's Party (CHP) engaged in making a report on ISIS activities in Adiyaman.
"When our son disappeared, we searched all over. For eight months we went to the border, gave his photograph to the governor. We advertised in newspapers as a missing person 10 times. We spoke with the prime minister at the AKP [Justice and Development Party] provincial assembly. The prime minister said to us, ‘I instructed the MIT [National Intelligence Organization] about your son.'
"I spoke with the middle man who took my son away. He promised us he would be back in 18 days. I went to the Akcakale police and gave them his photos. I went to the border crossing and pleaded with the police chief. He took me to [a crossing] where other families were waiting. I knew my son was at Tell Abyad. I stayed at Akcakale six days. I never saw my son," the source was quoted as saying in the CHP report.
The report claimed that around 400 people from Adiyaman have been recruited for ISIS and 60 of them are thought to be trained as suicide bombers.
21 of the said suicide bombers have been identified by intelligence services and photographs of 19 people have been released.
The first stop for those who join ISIS from Turkey is often Raqqa, Syria, where Dokumaci lives. They are trained as suicide bombers before returning to Turkey. They are chosen for the task because they know the country and can move about easily.
Hikmet Durgun of Russian Sputnik Media Group, who has reported extensively on IS, had warned of a possible suicide attack in Turkey before the Ankara bombing. Durgun told Al-Monitor that although the bombers are from Adiyaman, they usually aren't sent back there unless it is necessary. "They go to Ankara, Istanbul and Gaziantep," he said.
"The relatives of those who joined ISIS have been complaining bitterly about [Dokumaci]. The two bombers in the Ankara attack were also recruited by Dokumaci," reported Al-Monitor.
Abdurrahman Tutdere, a lawyer and member of the CHP team that wrote the report, said IS formed a recruitment system in Adiyaman.
Children from poor families are vulnerable to the ISIS recruitment team. They have set up a pipeline system. Those who go to ISIS for training come back and recruit more in Turkey.
Osman Suzen, the local head of the Human Rights Association, emphasized that the Dokumacilar Unit was exposed by the efforts of families of missing children.
