Mohammad Sharifullah has confessed to scouting out the route to the airport, where the suicide bomber later detonated his device among packed crowds trying to flee days after the Taliban seized control of Kabul, the Justice Department said.
Violence has waned in Afghanistan since the Taliban surged back to power and ended their insurgency in 2021, but the Islamic State (IS) group frequently stages gun and bomb attacks challenging their rule.
The efforts are led by a commission established under the Ministry of Information and Culture soon after the Taliban swept to power in 2021 and implemented their strict interpretation of Islamic law, or sharia.
Afghanistan is ranked as the country sixth most vulnerable to climate change and Taliban authorities have pushed to participate in COP summits, saying their political isolation shouldn't bar them from international climate talks.
