One detainee and several injured after attack during pro-Israel event in the U.S.

Washington, June 1 (EFE).- Colorado (U.S.) police arrested this Sunday a man accused of setting fire to several people in a commercial area of the city of Boulder during a pro-Israel march, an event that left multiple injured and that the FBI has already qualified as a "terrorist attack".

The authorities are "working" to identify the attacker and have not yet found a motive, according to Boulder Police Chief Stephen Redfearn, who reported this in a press conference.

"When we arrived at the area, we found several victims who have injuries consistent with burns," Redfearn recounted, adding that several people are seriously injured.

FBI Director Kash Patel announced this afternoon that his agency is already investigating the incident as a "deliberate terrorist attack" and deployed several agents to the region.

Politicians call the attack an act of hate

Authorities responded to emergency calls in the Pearl Street area of Boulder, a university town west of Denver, around 13:00 hours this Sunday (19:00 GMT).

Several of the injured were participating in a peaceful protest in favor of Israel, Redfearn detailed.

The Anti-Defamation League (ADL), an organization dedicated to combating "anti-Semitism" and promoting pro-Israel policies, confirmed on its X account that the attack took place during an event of the "Jewish community" to call for the release of the hostages who remain in the hands of Hamas, amid the ongoing Palestinian-Israeli conflict.

According to the website of the Colorado network of Jewish organizations, it was a walk that has been held periodically since the escalation of the conflict in Gaza on October 7, in "solidarity with the pain" of the hostages.

Several politicians, including Colorado Governor Jared Polis, made statements today calling the attack an act of "hate."

"My thoughts are with the people who have been injured and affected by this heinous act of terrorism," said Polis, of the Democratic party, in a post on X. "Acts of hate, of any kind, are unacceptable."

Hakeem Jeffries, the leader of the Democrats in the House, went a step further and called the attack "antisemitic".

"Antisemitism has no place in our nation, nor anywhere in the world. It must be eradicated," the legislator stated in a statement.
