The suspect in yesterday's attack in Boulder, Colo., was charged with a federal hate crime, and the attack is being investigated as an act of terrorism, authorities said.

• Mohamed Sabry Soliman, 45, yelled "Free Palestine!" as he threw Molotov cocktails into a crowd of people peacefully demonstrating for the release of Israeli hostages, according to an FBI affidavit.
• Authorities said Soliman told them after he was arrested that he had been planning the attack for a year. The demonstration he targeted was a weekly event organized by a group called Run for Their Lives.
• Eight people were hospitalized. No deaths have been reported.

President Trump blamed former President Biden for Soliman's presence in the country.

• "He came in through Biden's ridiculous Open Border Policy, which has hurt our Country so badly. He must go out under 'TRUMP' Policy," Trump wrote on Truth Social.
• Soliman entered the U.S. in August 2022 on a B2 visa that expired in February 2023, the Department of Homeland Security said.
