"Although the MOAB weapon leaves a large footprint, it is discriminate and requires a deliberate launching toward the target", the review said, using the acronym for the bomb. He added that this bomb, the largest non-nuclear bomb in the United States' arsenal, which has never been used, "is the right munition to reduce these obstacles and maintain the momentum of our offensive".

The strike in Afghanistan follows last week's death of a USA special forces soldier fighting IS in Nangarhar. The weapon was brought into Afghanistan specifically for this mission.

"US forces took every precaution to avoid civilian casualties with this strike".

Speaking by phone from Achin, Sher Nabi, a commander with the Afghan Local Police, said the bomb landed about a half-mile outside the town of Shogal, near the border with Pakistan.

"President Trump owes the American people an explanation about his escalation of military force in Afghanistan and his long-term strategy to defeat ISIS", she said in a statement. The extremist group established themselves there in January 2015, naming themselves Khorasan, an old name for Afghanistan, and were the first major militant group to challenge the Taliban.

However, the attack pales in comparison to an accidental explosion that rocked a coastal town almost three decades before the first atomic bomb.

The Air Force calls it the Massive Ordnance Air Blast bomb.

Afghanistan was ISIL's first foray outside the Arab world.

The United States dropped a 22,000-pound bomb on an ISIS cave complex in Afghanistan on Thursday afternoon, ABC News reported. It was unclear what the GBU-43 strike accomplished, as the bomb is not created to penetrate hardened targets such a bunkers or cave complexes.

The President has granted military commanders broader latitude to act independently on several battlefields where USA forces are involved, which Trump touted as making a "tremendous difference" in the fight against ISIS. He said he's given the military "total authorization", apparently referencing actions against ISIS in general, and praised the "incredible leaders" of the military.

To illustrate how big the GBU-43 conventional ordnance is, a Tomahawk cruise missile - the type of munition recently launched from USA warships into Syria in response to a chemical attack - weigh about 1,000 pounds.

The military also deployed it in the 1991 Gulf War and in Afghanistan in 2001.
