ISIS demonstrates monstrous new execution method in sickening propaganda video
MURDEROUS ISIS jihadists have developed a sick new method of execution, crushing prisoners to death using boulders.
A disgusting propaganda film shows masked militants killing three captured Yemini soldiers in different, cold-blooded ways.
One is beheaded before another is tied to a chair and shot dead, seconds after the terrified prisoner pleads for mercy.
A third man is made to lay his head on a rock before his skull is crushed by a large boulder.
The sick video, entitled "Crush Your Enemies", also shows a suicide bomber calling himself Abu Hanifa al-Holandi blowing himself up close to Yemen's presidential palace in the constitutional capital of Sana'a.
He has since been identified as a Dutch student named Mazen, who is belived to have told his parents he was travelling to Yemen to study Arabic.
The brainwashed youngster's grieving father told reporters in the Netherlands he had no idea his son had joined ISIS.
He said: "He liked playing football and had friends.
"He's a good boy, everyone knows that.
He's a good boy, everyone knows that
"When it happened, his friends all came here. They didn't believe it either."
ISIS expanded into Yemen in 2015, exploiting the chaos brought on by the civil war that has raged since Shia Islamists staged a coup against the government.
Additional footage in the jihadists' new film shows a line of militants standing in in a row amidst rocky terrain, with an overweight extremist in the middle.
It has been suggested he is the notorious ISIS executioner known as the Bulldozer, who has previously been filmed carrying out gruesome beheadings in Iraq.
