An Islamic State (IS) activist from Kerala is believed to have been killed along with 36 IS militants when the USA unleashed a massive GBU-43 bomb, also known as the "mother of all bombs", on the terror group's position in a cave network in eastern Afghanistan.
The office of President Ashraf Ghani said there was "close coordination" between the USA military and Afghan government over the operation in Achin.
The number of Islamic State fighters killed by the massive U.S. bomb has almost tripled to at least 90, Afghan officials said on Saturday.
The commander of US forces in Afghanistan, Gen. John Nicholson, said in a statement Thursday that it was the "right munition" to use to destroy the militants' network of tunnels in the area. The Massive Ordnance Air Blast (MOAB), as it is officially called - or the "Mother of all bombs", as it's become known - sent a mushroom-like cloud towering into the sky.
Nangarhar borders Pakistan and is a hotbed of militancy.
The statement by the spokesperson for the governor of Nangarhar came after an Afghan Ministry of Defense official said on Friday that ongoing clearance and assessment of the bomb site in the Achin district of Nangarhar indicated that the number of dead could rise. "And with the maximum amount of caution so that we don't cause civilian casualties".
Afghan President Ashraf Ghani said he approved of the strike, and it was created to support Afghan and U.S. forces conducting clearance operations in the region.
Pakistani villagers living near the Afghan border said the explosion was so loud they thought a bomb had been dropped in their village by USA planes targeting terrorists in Pakistan.
"They killed our women, youths and elders, sitting them on mines", Hakim added.
The strike was part of a joint operation by Afghan and global troops, Afghan President Ashraf Ghani's office said in a statement.
"The whole house was shaking", said Mufti Khan of Achin district in Nangarhar. Nangarhar provincial spokesman Attaullah Khogyani, however, said some 90 terrorists were killed.
Trump hailed the mission in Achin district as "very, very successful".
USA military authorities in Afghanistan estimate that ISIS could have up to 800 fighters in the country, with most operating in the remote eastern Nangarhar province.
Afghan officials say dozens of ISIL fighters were killed by the Pentagon's massive bombing.
IS, notorious for its reign of terror in Syria and Iraq, has made inroads into Afghanistan in recent years, attracting disaffected members of the Pakistani and Afghan Taliban as well as Uzbek Islamists. It has steadily lost territory and fighters to U.S. air strikes and an assault by Afghan forces on the ground. According to reports, the attack was able to decimate a deep tunnel of ISIS group.
