The wife and five children of Mohamed Soliman—the suspect accused of carrying out a terrorist attack in Boulder, Colorado—have been detained by U.S. Immigration and Customs Enforcement (ICE) and Homeland Security Investigations (HSI).

According to a senior official at the Department of Homeland Security (DHS), the family is being processed for expedited removal from the United States.

Soliman, an Egyptian national, was arrested Sunday after allegedly hurling multiple Molotov cocktails into a crowd during a pro-Israel demonstration outside the Boulder County Courthouse.

The violent attack left twelve people injured, including several burn victims.

Two remain hospitalized as of the latest reports.

According to court documents, Soliman had been residing in Colorado Springs and had entered the U.S. on a B1/B2 tourist visa, which expired in early 2023.

Though he was granted temporary work authorization later that year, it expired in March 2025. Officials confirmed that Soliman’s presence in the U.S. had since become unlawful.

Federal authorities say Soliman had been planning the attack for at least a year, deliberately postponing it until after his daughter graduated from high school just days earlier.

During interviews with investigators, Soliman reportedly admitted he disguised himself as a landscaper before launching incendiary devices into the group.

He told officers he intended to kill “Zionist people,” expressed no remorse, and stated that he would commit the attack again if given the opportunity.

“This was not a spur-of-the-moment act,” officials said. “It was premeditated and executed with clear intent to cause harm.”

Video footage and witness statements described moments of chaos and panic as flames erupted among demonstrators. Omer Shachar, a local leader of Run for Their Lives, the organization hosting the event, described the horrific scene.

The peaceful demonstration had been part of a weekly awareness campaign held by Run for Their Lives, which advocates for the release of Israeli hostages held by Hamas since October 7, 2023.

The group attracts a diverse cross-section of participants including Jewish and non-Jewish supporters, Americans and non-Americans, as well as individuals across political and religious lines.

Following the attack, the organization has temporarily paused its weekly walks while evaluating safety and security protocols.

However, Shachar emphasized that their mission remains unchanged.

“As long as it’s possible and we’re working with law enforcement, I will continue to walk,” he said. “I will walk until the last hostage is brought home.”

In a statement issued Monday, Secretary of State Marco Rubio addressed the broader national security implications of the incident:

“In light of yesterday’s horrific attack, all terrorists, their family members, and terrorist sympathizers here on a visa should know that under the Trump Administration we will find you, revoke your visa, and deport you.”

Soliman is currently facing multiple federal and state charges, including attempted murder, terrorism-related offenses, and use of incendiary devices.

Investigators are also reviewing surveillance footage and digital evidence to determine if others may have assisted or supported the attack.

The case remains under active investigation.
