Sharifullah was scheduled to appear before a Virginia court on March 5, facing charges filed by the U.S. Department of Justice for his role in a deadly conspiracy, according to U.S. officials.
He had confessed to FBI investigators that he aided in planning the Kabul airport bombing, providing critical assistance to the suicide bomber. Reports indicate that Sharifullah guided the attacker along the route while monitoring U.S. and Afghan checkpoints.
Sharifullah identified the bomber as Abdul Rahman, who ultimately carried out the attack. Investigations also linked him to an assault on a Russian city hall in Kirov, as well as several other attacks.
If convicted, Sharifullah could face a life sentence.
