SEATTLE, United States (AFP) — A mass shooting near the Space Needle landmark in Seattle killed three people on Sunday and wounded at least four others, including a toddler, according to the police.

Seattle Police said one suspect has been arrested and they are searching for another following the incident at a food festival in a popular tourist district of the northwestern United States city.

Assistant police chief Tyrone Davis said shots were heard around 6 p.m. and “there were two people who we believe were shooting at each other.” Two weapons were recovered.

There is “no outstanding threat to the community,” he said.

Seattle Police said three people had died.

Police said on X earlier Sunday there were “multiple shooting victims” after shots were fired at the Seattle Center.

Washington Governor Bob Ferguson said State Patrol SWAT officers had been deployed to assist local police.

“My prayers are with the families of the victims, and the responders as they work to keep people safe,” he said on X.

Mayor Katie Wilson said the shooting was “an act of horrific violence.”

“Our attention belongs to the people whose lives were taken, those fighting to recover, and the families beside them,” she said in a statement.

She also expressed her thanks to “the Seattle police officers who responded to the scene and took a suspect into custody.”

Four patients were being treated at the trauma center facility at Harborview Medical Center, according to spokesperson Susan Gregg: a child, a woman of unknown age who was in surgery, a 23-year-old man and a 39-year-old woman.

Davis said those in the hospital were in a “stable condition.”

Several witnesses told Seattle television station KIRO they heard multiple shots before running away.

“At first, I thought there were fireworks, and then everybody flooded and ran past us,” Nick Bate told the station.

“We started running. I didn’t know. I didn’t look where the person was going. I just heard everything,” a witness told Agence France-Presse.

The shooting took place during the “Bite of Seattle” summer festival celebrating local businesses and food vendors.
