Army Gen. John W. Nicholson, commander of US forces in Afghanistan, said in a written statement that the strike was created to minimize the risk to Afghan and USA forces conducting clearing operations in the Achin area "while maximizing the destruction" of IS fighters and facilities. America has concentrated on fighting them while also supporting Afghan forces against the Taliban.
USA forces dropped the GBU-43 Massive Ordinance Air Blast, a nine-meter giant weighing about 10 tons, on the Achin district of Nangarhar province Thursday night.
The number of jihadists killed when the U.S. dropped the "Mother Of All Bombs" on Afghanistan has risen to 90. It did not provide any details on how many of these bombs exist. It is Global Positioning System enabled and can target with smarter and improved accuracy.
The bombing - along with the first U.S. military strikes against the Syrian regime last week - mark a dramatic change in attitude for Trump, who advocated an isolationist, "America first" foreign policy during his election campaign.
Some Afghans remain deeply suspicious of Washington's motives in sending troops to the country more than 15 years ago, and view their ongoing presence as a form of occupation.
According to CNN national security analyst Peter Bergen, "the war in Afghanistan is at its lowest point for the Afghans and their American allies since the Taliban were overthrown in the months after 9/11". "Bunker Busters" were used on targets in Baghdad during the USA invasion of Iraq in 2003.More news: Holiday Inn admits credit card-stealing malware hit 1200 locations
The GBU-43, a non-nuclear, 10-tonne missile powered by a wave of air pressure, was dropped on Thursday onto caves used by the terror group.
But the massive blast still terrified villagers 20 miles away across the border in Pakistan. At 30,000 pounds, it is even heavier than the GBU-43 but carries less explosive power. Pentagon video showed the bomb striking a mountainside overlooking a river valley with a giant blast that overwhelms the landscape and sent up a massive column of black smoke. The dead included the brother of the late IS leader Hafiz Saeed, who was killed in a United States air strike past year, officials said.
Although powerful, the size of that explosion pales in comparison to that of a nuclear bomb.
Khogyani said that the latest death figure was received from Afghan military personnel involved in clearance operations and assessment of the site following the massive blast attack.
ISIL's Amaq News Agency said no fighters were killed.
Soon after the attack, a US commander in Afghanistan said that the bomb had achieved it intended goal, implying that the tunnel had been destroyed. "If big bombs were the solution we would be the most secure place on earth today".
