Recent footage emerging online shows bungling Islamic State of Iraq and Syria (ISIS) fighters accidentally blowing themselves up in combat.
In one online video, a fighter firing a mortar dies after the weapon explodes because he reloaded it too quickly.
In another, a militant detonates a bomb during a group picture with other militants. Another shows a fighter firing a Kalashnikov assault rifle, only to see it disintegrate in his hands.
Since the release of the gruesome video showing the burning to death of captured Jordanian fighter pilot Moaz al-Kasasbeh by militants, the online clips have become popular.
Some have been edited into compilations in the style of a U.S. home movie clip show – with game-show music as a soundtrack.
“These amateurs would find a way to nuke their own soldiers if given the chance,” wrote on YouTube user.
