One death has been reported and about 21 others were injured in a shooting in Missouri at the end of the Kansas City Chiefs’ Super Bowl victory parade.
Officials said they treated eight victims who were in immediately life-threatening condition and seven others who had suffered injuries that could be critical.
Police said they have arrested three suspects in connection to the shooting.
At a news conference on Wednesday, Kansas City Police Chief Stacey Graves said a total of 22 people were struck by gunfire, and one died.
Ms Graves said they responded immediately after the gunshots broke out and detectives who were on the scene quickly opened an investigation.
The surviving victims were transported to three local hospitals, according to the officials.
Local hospitals said they were also treating people who were not shot, but who had suffered other injuries in the chaos after the shooting.
The shots were fired west of Union Station, the train station in downtown Kansas City, which was where the parade ended at about 14:00 local time (20:00 GMT).
The gunfire caused the watching crowd, including the city’s mayor and his family members, to run for cover.
In a statement, US President Joe Biden re-echoed his stance on gun violence.
“Today’s events should move us, shock us, shame us into action,” he said, as he called for gun reform and a ban on assault rifles in the US.
