The Trump administration has dispatched federal immigration officers in Colorado to arrest the wife and children of Boulder attack suspect, Mohamed Sabry Soliman.

Homeland Security Secretary Kristi Noem announced on Tuesday afternoon that U.S. Immigration and Customs Enforcement had moved to take into custody the family of Soliman, who was arrested and charged for using a flamethrower to injure 12 people during Sunday’s attack on Pearl Street Mall, where demonstrators were gathering for a weekly “Run for Their Lives” event demanding the release of Israeli hostages held by Hamas. Witnesses and investigators say Soliman shouted, “Free Palestine” and “End Zionists” during the assault.
