Leaked Isis recruitment documents suggest an NHS doctor left his family in the UK to join Isis in Syria.
Issam Abuanza, 37, left his wife and two children at home in Sheffield to travel to Syria in 2014, the BBC reports.
After crossing in to Syria, he filled out a registration form, telling his Isis handlers he was a doctor specialising in endocrinology - the diagnosis and treatment of diseases related to hormones.
Images on his Facebook account show him wearing doctors' scrubs and carrying a handgun in a holster, as he smiles and raises his index finger in the air in a gesture commonly associated with Isis.

Another photo shows him dressed him combat fatigues, reading the Quran with an AK-47 assault rifle resting against his body.
In February 2015, he posted about the burning to death of a captured Jordanian pilot by Isis, writing: "I would've liked for them to burn him extremely slowly and I could treat him so we could torch him once more."
A month earlier, he celebrated the terror attack at the Paris office of the French satirical magazine Charlie Hebdo, writing: "Praise be to God for this terrorist act. God kill off their enemies, military and civilian, men and women, adult and children."
