This gun camera video from a U.S. Army Apache helicopter in Afghanistan shows just how one of those deadly those roadside bombs or improvised explosive devices (IEDs) backfired on the enemy. As two suspected insurgents apparently attempt to dig up an IED planted in the roadway, you can hear the Apache crew on their radio describing the scene to their ground commanders. As the helicopter crew prepares to attack, they're forced to hold their fire as a boy approches the suspected enemy. The boy leaves, but the crew is forced to hold fire again when a man approaches to fetch water from a nearby stream. Suddenly, without warning, there's a huge blast. It appears the two insurgents blew themselves up with an IED intended for American forces.
