Cholo Abdi Abdullah Convicted for Conspiring to Commit 9/11-Style Attack at the Direction of Al Shabaab

A jury returned a guilty verdict today against Cholo Abdi Abdullah, 34, on all six counts in the indictment, which included conspiring to provide, and providing, material support to a foreign terrorist organization; and conspiring to murder U.S. nationals, commit aircraft piracy, destroy aircraft, and commit transnational acts of terrorism. Abdullah is scheduled to be sentenced on March 10, 2025.

“The jury found that Cholo Abdi Abdullah, an operative of the terrorist organization al Shabaab, conspired to murder Americans in a terrorist attack reminiscent of the September 11 attack on our country,” said Attorney General Merrick B. Garland. “Today’s conviction ensures that Abdullah will spend decades in prison for his crimes. The Justice Department will never stop working to identify, investigate, and prosecute those who would use heinous acts of violence to harm the American people. It does not matter where terrorists hide, they will not evade the long arm of the law.”

“Today, the jury returned a unanimous verdict holding Cholo Abdi Abdullah responsible for trying to replicate one of history’s most heinous acts of terrorism,” said U.S. Attorney Damian Williams for the Southern District of New York. “Abdullah trained with al Shabaab for months in Somalia to become a deadly terrorist, and then spent months at flight school preparing to hijack a commercial aircraft to crash it into a building in the United States. Abdullah relentlessly pursued his goals and was on the cusp of getting a commercial pilot license while conducting extensive attack planning, such as how to breach an airplane cockpit door. I commend the tireless work of our federal law enforcement partners and the career national security prosecutors of this office. This effort has been carried forward by generations of agents and prosecutors who never relented in their effort to bring Abdullah to justice and keep this nation safe. Thanks to their work and today’s verdict, Abdullah will now serve a lengthy sentence in federal prison.”

According to the indictment and the evidence presented at trial, Abdullah was an operative for the foreign terrorist organization Harakat al-Shabaab al-Mijahideen, commonly known as “al Shabaab,” based in Somalia. After training with al Shabaab for months with AK-47 assault rifles and explosives at a series of safe houses in Somalia, Abdullah participated in a plot to hijack a commercial aircraft and crash it into a building in the U.S. He spent months at a flight school in the Philippines working toward a commercial pilot license, and researched how to obtain pilot jobs, targets such as the tallest buildings in a major American city, transit visas to the U.S., and how to open a cockpit door from the outside. Abdullah also sent encrypted messages reporting his progress to his al Shabaab handler, including his extensive research on post-September 11 hijackings.

Abdullah conspired to commit this attack on behalf Al Shabaab, which has sworn allegiance to al Qaeda and is responsible for numerous deadly terrorist attacks, including attacks that have claimed American lives. Starting in or about 2019, al Shabaab embarked on a string of terrorist attacks as part of an operation in response to the U.S.’s decision to move its embassy in Israel to Jerusalem, which the group has dubbed “Operation Jerusalem Will Never be Judaized.” In particular, these terrorist attacks perpetrated by al Shabaab included an attack on Jan. 15, 2019, at a hotel in Nairobi, Kenya, which resulted in the deaths of approximately 21 people, including a U.S. national and survivor of al Qaeda’s September 11 attack on the World Trade Center in New York; a Sept. 30, 2019, attack on a U.S. military facility in Somalia; and a Jan. 5, 2020, attack on another U.S. facility in Kenya, in which three Americans were killed.  

Abdullah was convicted on six counts: conspiring to provide material support to a foreign terrorist organization, for which he faces a maximum penalty of 20 years in prison; providing material support to a foreign terrorist organization, for which he faces a maximum penalty of 20 years in prison; conspiring to murder U.S. nationals, for which he faces a maximum penalty of life in prison; conspiring to commit aircraft piracy, for which he faces a mandatory minimum penalty of 20 years in prison and a maximum penalty of life in prison; conspiring to destroy aircraft, for which he faces a maximum penalty of 20 years in prison; and conspiring to commit acts of terrorism transcending national boundaries, for which he faces a maximum penalty of life in prison.
