Police in Boulder, Colo., said Sunday that a suspect is in custody after reports that someone was setting people on fire.
Earlier, police said there were “several victims” in the attack without providing further details.
Although the FBI immediately described the incident as an act of terror, Boulder police Chief Steve Redfearn said it was “irresponsible for me to speculate on motive this early on.”
The attack took place at a pedestrian mall where demonstrators had gathered to call for the release of hostages who remain in Gaza.
More to come.
