A newly released Isis training video shows jihadist fighters kicking each other in the groin and playing leapfrog.
The 14-minute footage gives insights into the militant group’s training regime.
Around 20 recruits can be seen performing training exercises in a grassy clearing in a wooded area.
Each fighter is dressed in identical navy blue and grey camouflage, with black bandanas and headbands styled after the Isis flag.
As well as doing sit-ups with boulders on their chest, the recruits are kicked in their thighs and groins by an instructor, presumably to improve their endurance.
