Mannen som sprengte seg selv i lufta i den tyrkiske grensebyen Suruc mandag og tok 31 andre med seg i døden, var en tyve år gammel kurdisk student fra det sørøstlige Tyrkia.
DNA-tester har bekreftet identiteten.
PKK påtok seg onsdag ansvaret for drapene på to politimenn, som hevn for massedrapene i Suruc.
Turkish authorities said DNA tests had confirmed that the Suruc bomber was a 20-year-old man of Kurdish origin born in Adiyaman.
Seyh Abdurrahman Alagoz’s mother told the newspaper Radikal (in Turkish) that her son was a former student at Adiyaman university who had gone «abroad» six months ago with his brother.
«I don’t know what they were doing abroad, they never said. They were just telling me they were fine,» Semure Alagoz said.
A senior Turkish official told Reuters that he believed the bomber, who he did not name, had travelled to Syria last year with the help of a group linked to IS militants.
