For All the World to See: Video Shows Massive Bomb Strike

The "mother of all bombs" was unleashed Thursday on an ISIS target, and by Friday morning, the Defense Department had a short video up on Twitter showing the strike. The 30-second clip was embedded in a tweet that described the strike as hitting "#ISIS cave and tunnel systems in eastern #Afghanistan" and "designed to minimize risk to Afghan and US Forces." The falling bomb is briefly visible in the video, which shows the weapon detonating above the ground; Fox News reports the impact zone measured more than a mile in width.

The weapon, otherwise known as the GBU-43/B Massive Ordnance Air Blast, or MOAB, was so big it had to be dropped out the rear of an Air Force C-130 cargo plane. "We kicked it out the back door," a US official says. (More Afghanistan stories.)
