A GBU-43/B Massive Ordnance Air Blast Bomb (MOAB), nicknamed the “mother of all bombs,” was dropped at 7:32 p.m. local time, according to four US military officials with direct knowledge of the mission. A MOAB is a 30-foot-long, 21,600-pound, GPS-guided munition.
President Donald Trump called it “another successful job” later Thursday.
The bomb was dropped by an MC-130 aircraft, stationed in Afghanistan and operated by Air Force Special Operations Command, Pentagon spokesman Adam Stump told CNN.
Officials said the target was an ISIS cave and tunnel complex and personnel in the Achin district of the Nangarhar province.
“The United States takes the fight against ISIS very seriously and in order to defeat the group we must deny them operational space, which we did,” White House press secretary Sean Spicer said later Thursday. The strike “targeted a system of tunnels and cave that ISIS fighters use to move around freely.”
Afghanistan’s ambassador to the US, Hamdullah Mohib, told CNN’s Brooke Baldwin that the bomb was dropped after fighting had intensified over the last week between US Special Forces and Afghan troops against ISIS.
The US and Afghan forces were unable to advance because ISIS had mined the area with explosives, so the bomb was dropped to clear the tunnels, Mohib said.
Trump declined to say whether he personally signed off on the strike, but did comment, “Everybody knows exactly what happens. So, what I do is I authorize our military.”
He continued, “We have given them total authorization and that’s what they’re doing.”
The President has granted military commanders broader latitude to act independently on several battlefields where US forces are involved, which Trump touted as making a “tremendous difference” in the fight against ISIS.
Gen. John Nicholson, commander of US forces in Afghanistan, signed off on the use of the bomb, according to the sources. The authority to deploy the weapon was granted to Nicholson by the commander of US Central Command, Gen. Joseph Votel, Stump said.
This is the first time a MOAB has been used in the battlefield, according to the US officials. This munition was developed during the Iraq war and is an air blast-type warhead that explodes before hitting the ground in order to project a a massive blast to all sides.
As originally conceived, the MOAB was to be used against large formations of troops and equipment or hardened above-ground bunkers. The target set has also been expanded to include targets buried under softer surfaces, like caves or tunnels.
“As ISIS-K’s losses have mounted, they are using IEDs, bunkers and tunnels to thicken their defense,” Nicholson said in a statement following the strike.
“This is the right munition to reduce these obstacles and maintain the momentum of our offensive against ISIS-K,” Nicholson added.
“US forces took every precaution to avoid civilian casualties with this strike. US Forces will continue offensive operations until ISIS-K is destroyed in Afghanistan,” read the statement from US Forces Afghanistan.
The extent of the damage and whether anyone was killed is not yet clear. The military is currently conducting an assessment.
The Pentagon is currently reviewing whether to deploy additional trainers to Afghanistan to help bolster US allies there.
There are about 8,400 US troops in Afghanistan and they regularly perform counterterrorism operations against ISIS in the Nangarhar Province.
The US counterterrorism mission is separate from the NATO-led effort to train, advise and assist the Afghan army and police force.
While ISIS is identified primarily with its presence in Iraq and Syria, US and coalition officials have long expressed concern about a growing presence in Afghanistan.
ISIS first emerged in the summer of 2015 in the country’s east, fast gaining ground and support, often among disaffected Taliban or Afghan youth.
The Afghan offshoot’s link to the organization’s Syria-based leadership has been questioned. Many say in fact the Afghan ISIS fighters came from Pakistan and adopted the group’s branding in order to get financing.
