IS release new video showing 'British boy blowing up prisoners'

Islamic State (IS) has released a new video purportedly showing a young British boy blowing up a car and killing three prisoners inside.
The boy, who is thought to be four-year-old Isa Dare, is apparently shown with his hand on the detonator before shouting “Allahu Akbar” – God is great – next to the burnt wreckage.
