'Jihadi John': Mohammed Emwazi's father 'condemned son as dog' and hoped 'he would be killed' after he fled to Syria

Colleague says Emwazi's father was distraught after his son was identified as British Isis militant

26-year-old 'Jihadi John' is believed to have left Britain in 2012-13

The father of the British man unmasked as Jihadi John reportedly condemned his son as a "dog, an animal and a terrorist" and hoped he would be killed after he fled to Syria.

Mohammed Emwazi’s father blasted his son in a tearful phone call with a colleague to explain his absence from his job in a Kuwait supermarket, The Telegraph reports.

His son had been identified in reports as the notorious hooded militant who appeared in videos showing the brutal beheading of journalists and aid workers.

His colleague Abu Meshaal said it was a “catastrophe” for Emwazi’s family.

“He said he had talked to him a lot trying to persuade him to return to his personal life but that the son didn't listen to him. He said, 'To hell with my son'."

He said Emwazi son had called him to ask for his parent’s blessing to travel to Syria for "jihad" in 2013.

"Mohammed called his father and said 'I'm going to Syria to fight jihad, please release me and forgive me for everything'," Mr Meshaal said. "Jassem said, "f*** you. I hope you die before you arrive in Syria."

He described Emwazi's father as a a "respectable and polite" man who commutes 30 miles to get to work in a remote desert region every day.

Mr Meshaal said he had not returned to work since the news broke on Thursday, despite assurances from his employers that he is free to return to his job.
