Authorities claim that Mohamed Sabry Soliman executed a violent act against a peaceful pro-Israel demonstration on Sunday, labeling it as a terror attack that resulted in injuries to 12 people.

Soliman arrived in the United States in August 2022 on a B1/B2 visa, expected to depart by February 2023. However, the Biden administration extended his work authorization until March 2025, just two months prior to him being accused of injuring 12 individuals during a peaceful pro-Israel protest in Boulder, Colorado.

Reportedly, Soliman confessed to federal and local authorities that he targeted a “Zionist group” in Boulder, aiming to hinder their efforts, as he believed they were encroaching on “our land,” which he referred to as “Palestine.” Soliman allegedly stated he had been plotting the attack for a year, opting to wait until after his daughter’s graduation to proceed with his plans.

Here’s a timeline of Soliman’s journey to the United States:

– Spring 2023: Soliman begins driving for Uber

Soliman began driving for Uber in the spring of 2023, a spokesperson for the company told Fox News Digital. Uber said Soliman met all requirements to drive for the company, which include passing a criminal and driving history background check, holding a valid Social Security number and providing a photo ID.

One of Soliman’s neighbors told Fox News Digital that Soliman was “not home that often” because he was “working really hard.”

– May 2023: Soliman began working at Veros Health

A Veros health spokesperson told Fox News Digital that Soliman began working at the company in its accounting department.

“He was hired in our accounting department. He went through a hiring process with ADP, our employer [Professional Employer Organization]. At the time of hire, he was confirmed to have a valid work visa, which was noted to expire in March 2025,” the spokesperson said.

– March 2025: Soliman’s work authorization in the United States ended

Soliman’s work authorization ended in March 2025 after it was granted under the Biden administration in March 2023, sources said.

– June 1, 2025: Soliman accused of throwing Molotov cocktails at pro-Israel group

Soliman was accused of throwing Molotov cocktails at the pro-Israel group “Run for Their Lives” as they were protesting for the release of Hamas’ hostages. Twelve people were injured.

Soliman was charged with first-degree murder, crimes against at-risk adults/elderly; first-degree assault, criminal attempt to commit class one and class two felonies, and use of explosives or incendiary devices during a felony.

Former FBI special agent Jonathan Gilliam told Fox News Digital he’s concerned the Biden administration didn’t do a good enough job at vetting Soliman when he first came to the United States.

“When we look at the border and how open the border was for over four years, literally wide open,” Gilliam said. “The problem with individuals like this guy…is that they are presenting themselves as activists. They’re presenting themselves as altruistic and acting out for a cause for the greater good.”

Gilliam said it’s likely Soliman has harbored “hatred” for a period of time, but chose to act out on it now.

“He came from an area where the hate is taught his entire life, of America, of Israel,” Gilliam said. “He planned the event for a year, but he already had the hatred inside of him. So you’re just seeing them act out on something that is already inside of them.”
