The Kabul Tribune (KT) — An Afghan man arrested last year in connection with the 2021 suicide bombing at the Kabul airport was sentenced Wednesday to 20 years in federal prison after being convicted of providing material support to the Islamic State group’s Afghanistan affiliate.

According to ABC, Mohammad Sharifullah was convicted in April by a federal jury after telling FBI investigators that he had helped ISIS-K plan dozens of attacks over roughly a decade.

The jury, however, could not reach a unanimous decision on whether Sharifullah’s support directly contributed to the Aug. 26, 2021, suicide bombing at Hamid Karzai International Airport. The attack killed 13 U.S. service members and about 160 Afghan civilians during the chaotic U.S. withdrawal from Afghanistan.

Defense attorneys argued that the government had no direct evidence tying Sharifullah to the Abbey Gate attack other than his statements to the FBI. They also argued that the statements may have been made under duress because Sharifullah was interviewed after being arrested by Pakistani authorities, whom the defense accused of having a history of torturing terrorism suspects.

At Wednesday’s more than two-hour sentencing hearing, U.S. District Judge Anthony Trenga said the government had presented sufficient evidence for him to consider Sharifullah’s role in the Abbey Gate bombing alongside his admitted involvement in other attacks carried out during his years as an ISIS-K member.

Family members of the 13 U.S. service members killed in the bombing addressed the court and urged Trenga to impose the maximum sentence of 20 years.

“No justice will be enough to mend my broken heart,” said Paula Knauss, the mother of Army Staff Sgt. Ryan Knauss.

Alicia Lopez, the mother of Marine Cpl. Hunter Lopez, described Sharifullah as responsible for setting in motion events that led to her son’s death.

But Mark Schmitz, the father of Marine Lance Cpl. Jared Schmitz, offered a different message. Addressing Sharifullah directly, Schmitz said he forgave him for his role in his son’s death.

“I forgive you,” Schmitz said. “I will not carry my hatred for you the rest of my life.”

Trump previously described Sharifullah as an “architect” of the Abbey Gate bombing when announcing his arrest during a joint address to Congress at the beginning of his second administration.

Trenga said there was “no doubt” that Sharifullah was a “dedicated terrorist” and expressed frustration that federal law limited the sentence to a maximum of 20 years.

“If I could pose a sentence separately for each of your victims, I would,” Trenga said.

Sharifullah declined to address the court through an interpreter. He showed no visible reaction as relatives of the victims spoke or as the judge announced his sentence.
