LOS ANGELES - Eight people were injured Sunday in "a targeted terror attack" in Boulder, Colorado, authorities said.

The suspect was identified as Mohamed Sabry Soliman, said Mark Michalek, special agent in charge of the FBI's Denver office, on Sunday evening at a news conference.

Boulder police confirmed Sunday night that eight people, namely four women and four men, were injured in the attack. Officials initially told news outlets that six victims had been taken to hospitals.

The 45-year-old suspect was allegedly heard yelling "Free Palestine" while using a "makeshift flamethrower" during the attack. He was also reportedly heard yelling "They are killers" and "How many children you killed."

Boulder Police Chief Stephen Redfearn said at a news conference that Boulder dispatch received several calls reporting an incident at the county courthouse in downtown Boulder at approximately 1:26 pm local time (1926 GMT).

Police officers found several victims suffering from burns and other injuries upon arriving at the scene.

An organizer with Run For Their Lives, a group that holds weekly walks to raise awareness about Israeli hostages held in Gaza -- told local television station KUSA that a man was waiting with bottles when they arrived at the historic courthouse near 13th and Pearl Streets.

The suspect threw the bottles, burning multiple people, including a woman who was severely injured and had to roll on the ground to extinguish the flames, according to the report.

One of the victims is a Holocaust survivor, said the report.

In a social media post, FBI Director Kash Patel said, "We are aware of and fully investigating a targeted terror attack in Boulder, Colorado."

White House deputy chief of staff for policy and homeland security advisor Stephen Miller said in a social media post that the terror attack was committed by "an illegal alien."

Fox News reported that Soliman is an Egyptian national who overstayed his visa after entering the United States, citing Homeland Security and U.S. Immigration and Customs Enforcement sources.

CNN reported authorities are working to determine whether the suspect may have suffered mental health issues.

"He's shirtless, screaming, used rudimentary (explosive) devices, and stuck around to be arrested," a source told CNN.

Colorado Governor Jared Polis condemned the attack as a "heinous and targeted act on the Jewish community" in a statement.

"Hate is unacceptable in our Colorado for all, and I condemn this act of terror. The suspect should be prosecuted to the fullest extent of the law," he added.
