Achin District
Achin is a district in southern Nangarhar Province, Afghanistan, on the border with Pakistan.
Its population is 100% Pashtun. Achin is home to the Shinwari tribe, one of the largest Pashtun tribes.
It was a stronghold of the Mujaheddin during the Soviet occupation of Afghanistan in the 1980s.
During the April 2017 Nangarhar airstrike, the United States Air Force dropped a MOAB in Achin district which targeted a tunnel complex of the ISIS-affiliate located in the area, and reportedly killed dozens of militants.
