Review says 2021 deadly Kabul bombing wasn't preventable 

FILE - A screen grab shows people carrying an injured person to a hospital after an attack at Kabul's airport, in Kabul, Afghanistan Aug. 26, 2021. An Islamic State offshoot claimed responsibility for deadly suicide attacks outside the airport.

The suicide bombing at the Kabul airport that killed U.S. troops and Afghans in August 2021 was not preventable, and the "bald man in black" spotted by U.S. service members the morning of the attack was not the bomber, according to a new review by U.S. Central Command.
