Unconfirmed reports from Syria claim
The gigantic bomb, officially the Aviation Thermobaric Bomb of Increased Power (ATBIP), is also know as the "Father of All Bombs" (FOAB). FOAB is a so-called thermobaric weapon, a type of munition that releases a cloud of flammable gas over the target before detonating it. In addition to the heat of the explosion, this approach also creates a deadly pressure wave that is particularly damaging against enclosed spaces, including tanks, caves, and bunkers.
