A teenage  boy has been executed by a brutal ISIS butcher known as 'The Bulldozer' for listening to Western pop music.

The cowering 15-year-old was publicly beheaded by the giant murderer, who wielded a huge sword as a crowd of locals looked on in Isis stronghold Mosul.

Pictures appear to show 'The Bulldozer', who carries out executions for the Islamic extremists using a giant sward, hiding his face behind a black balaclava like Brit terrorist Jihadi John.

The world first got a glimpse of him in June 2014 when he was pictured holding a 52kg anti-aircraft gun.

Reports from the captured northern Iraqi city said the boy, Ayham Hussein, was caught listening to music on a portable compact disc player by extremist henchmen.

After catching him listening to the western pop, Isis thugs detained the youngster inside his dad's market shop before beating him and trying him in a local sharia court - where he was sentenced to death.

A source told Kurdish media: "The boy was executed by beheading in a town square in the centre of the city."

The boy's death sparked outrage from many residents - with a number of angry locals staging a protest outside the family home.

Isis now impose death sentences for a number of "trivial crimes", which would previously have been punished by flogging.

An alternative healer who specialised in acupunture was recently murdered for being a sorcerer in front of a crowd of baying locals, who chanted "Allahu Akbar".

A refugee from Sirte, where the beheading took place, said: "I know that man personally. He is not a witch, he is just an alternative healer who does homeopathy and acupunture. He was wrongly accused."

Twelve more people were butchered for speaking out against Islam recently and teachers have been killed for refusing to teach radical Sharia law in schools.
