Fahad al-Hajiri, a Saudi high school student, was involved in a suicide attack at the beginning of this month after ISIS chose him and three others to carry out an operation inside an oilfield in Homs.
Hajiri, nicknamed Abu Azzam al-Sharqi, lived in Dammam, where he went to school, but he left his studies to fly to Syria and join ISIS.
Prior to his departure, Hajiri tried to communicate with members of ISIS in Syria via Internet, to arrange his stay there. He participated in a number of battles after he finished his intensive training, or what ISIS calls sharia training.
Abu Abdulrahman al-Mutairi, a man who fought with him for ISIS and has since returned, said they were told that they would "carry out the operation in Al-Shaer oilfield in rural Homs."
