The man suspected of being responsible for a fiery attack on Jewish protesters in Colorado was expected in court Monday, with the government saying he was in the United States illegally.
Mohamed Sabry Soliman is alleged to have thrown Molotov cocktails and sprayed burning gasoline in Boulder on Sunday at a gathering in support of Israeli hostages held by the Hamas armed group.
Eight people were hurt in the attack -- four men and four women -- with the oldest reportedly being 88 years old.
FBI agent Mark Michalek said the suspect used "a makeshift flamethrower" and "was heard to yell: 'Free Palestine,'" which has seen him hit with hate crime charges, according to US media.
US Homeland Security officials said he was in the country illegally, having overstayed a tourist visa, but that he had applied for asylum in September 2022.
Police have released this booking photo of Mohamed Sabry Soliman, who is charged over the attack in Boulder.
President Donald Trump lashed out at his predecessor, Joe Biden, over the incident.
"Yesterday's horrific attack in Boulder, Colorado, WILL NOT BE TOLERATED in the United States of America," Trump said on his Truth Social network, describing it as a "terrible tragedy."
He blamed "Biden's ridiculous Open Border Policy" for allowing Soliman into the country.
"This is yet another example of why we must keep our Borders SECURE, and deport Illegal, Anti-American Radicals from our Homeland," he wrote.
The attack occurred on Sunday afternoon during a regular demonstration in support of hostages taken in the attack on Israel by Hamas gunmen on October 7, 2023.
In one video that purportedly shows the attack, a shirtless man holding bottles in his hands is seen pacing as the grass in front of him burns.
He can be heard screaming "End Zionists!" and "They are killers!" towards several people in red T-shirts as they tend to a person lying on the ground.
Other images showed billowing black smoke.
In another video, a police officer rushes to arrest the same man, who is lying on the grass. Several people are milling around nearby.
Boulder Police Chief Steve Redfearn told reporters that "at least one victim was very seriously injured, probably safe to say critical condition."
The suspect was also injured before being taken into custody, Redfearn said.
Boulder resident Alexis Cendon said he felt "very, very scared" after hearing about the attack near his workplace.
Sunday's attack occurred during the Jewish holiday of Shavuot. It comes almost two weeks after the fatal shooting of two Israeli embassy staffers outside a Jewish museum in Washington, where a 31-year-old suspect, who shouted "Free Palestine," was arrested.
Israel's top diplomat Gideon Saar condemned Sunday's "terrible antisemitic terror attack targeting Jews in Boulder."
Israeli Ambassador to the United Nations Danny Danon also voiced outrage.
"Terrorism against Jews does not stop at the Gaza border -- it is already burning the streets of America,"
he said in a statement.
