A wing of Sulaymaniah's military hospital has been sealed off and 24-hour security has been posted at the door of a ward.
Inside lies an injured young man; a very special patient and prisoner.
He is 23-year-old Horr Jaffer, from Chechnya, and he is an Islamic State (IS) suicide bomber.
His capture has been a secret until now.
Sky News is the first to get access to this man who was caught in the southern Kurdish town of Jalula after his bomb part exploded.
He had been attempting to destroy a Kurd checkpoint by driving a bomb-laden car into their midst. Under questioning he admits that he joined IS in Syria after his father, mother and six family members were killed there.
He says they had moved from Chechnya to Pakistan before going to Syria.
The Kurds believe his father and brothers were to all intents and purposes professional jihadists; moving to countries where they could ply their trade. That trade is killing people.
"I want to be a martyr. I decided after they killed my family," he says in barely audible Russian. They didn't tell me anything about what I was doing or where I was. I just had to press the button."
The killer claims that Syria is filling with foreign fighters; a constant stream from all over the world.
