Police in the US said a male suspect has been taken into custody after an attack that injured multiple people in Boulder, Colorado, in what the FBI director described as a "targeted" act of terror.
While stressing that the information was "very preliminary,"Boulder Police Chief Stephen Redfearn said that the man was apprehended following calls to the police dispatch of someone with a weapon who was "setting people on fire."
Mr Redfearn said he wasn't in a position to identify the suspect yet, noting that he’d been taken to the hospital.
He said there were multiple injuries among the victims, ranging "from very serious to more minor."
The Boulder attack occurred in the vicinity of a walk to remember the Israeli hostages who remain in Gaza.
FBI Director Kash Patel, in a statement, described the incident as a targeted terror attack and said agents were on the scene.

Mr Redfearn, however, said it was too early to speculate about a motive.
"We are not calling it a terror attack at this moment," he said.
"This was a beautiful Sunday afternoon in downtown Boulder on Pearl Street and this act was unacceptable," he said.
"I ask that you join me in thinking about the victims, the families of those victims, and everyone involved in this tragedy."
The incident comes amid heightened tensions in the United States over Israel's war in Gaza, which has spurred both a an increase in antisemitic hate crime as well as moves by conservative supporters of Israel led by President Donald Trump to branded pro-Palestinian protests as antisemitic.
His administration has detained protesters without charge and cut off funding to elite US universities that have permitted the demonstrations.

Brooke Coffman, a 19-year-old at the University of Coloradowho witnessed the Boulder incident, said she saw four women lying or sitting on the ground with burns on their legs.
One of them appeared to have been badly burned on most of her body andhad been wrapped in a flag by someone, she said.
She described seeing a man whom she presumed to be the attacker standing in the courtyard shirtless, holding a glass bottle of clear liquid and shouting.
"Everybody is yelling, 'get water, get water," Ms Coffman said.
Senate Minority Leader Chuck Schumer, a prominent JewishDemocrat, said he was closely monitoring the situation.
It also follows the arrest of a Chicago-born man in the fatal shooting of two Israeli embassy employees in Washington DC.
Someone opened fire on a group of people leaving an event hosted by the American Jewish Committee, an advocacy group that fights antisemitism and supports Israel.
The shooting fueled polarization in the United States over the war in Gaza between supporters of Israel and pro-Palestiniandemonstrators.
