() The man accused of attacking a crowd of people and injuring at least eight in Boulder, Colorado, has been charged with first-degree murder, according to booking documents.

Boulder County court records show 45-year-old Mohamed Sabry Soliman is facing eight felony charges, including murder in the first degree, though police have yet to publicly confirm any fatalities.

Soliman is accused of attacking a group of demonstrators Sunday using a makeshift flamethrower and an incendiary device. The group was gathered at an outdoor mall on Boulder’s popular Pearl Street to call for the release of Israeli hostages in Gaza.

As of Monday morning, law enforcement said four women and four men, ranging from ages 52 to 88, were injured in the attack.

Mark Michalek, the special agent in charge of the FBI’s Denver field office, said the suspect yelled “Free Palestine” during the attack.

Soliman, an Egyptian national identified by the White House as an “illegal alien” who overstayed his visa, was also hurt during the attack. He was medically evaluated before being booked into the Boulder County Jail, according to law enforcement.

It was unclear Monday morning if Soliman would face further charges in connection with the incident, which the FBI called a “targeted terror attack.”
