"Right now we're going room by room and evacuating every single person that's in that school," Sheila Miller, director of communications for the Bend Police Department, said Thursday. This is what we never want to happen in Bend. It is devastating."

Miller said authorities received a call at 12:59 p.m. local time (7:59 p.m. GMT) that shots had been fired at a car outside the school and arrived on the scene within minutes.

The suspect was shot and killed a short time later, though Miller said he did not know if police or a bystander subdued the assailant.

The number and condition of the injured have not yet been determined.

Federal Bureau of Investigation (FBI) Director Cash Patel said in a social media post that the agency was on the scene and assisting local law enforcement with the investigation.

"We will make available whatever resources they need," he wrote.

Oregon Governor Tina Kotek also said she was closely monitoring the situation.

Jeff Merkley, Oregon's U.S. Senate representative, was among the political leaders who offered condolences following the shooting.

"My heart goes out to the community of Bend and all the students and families affected," he wrote in a post on the X social network. No one should be afraid of school violence.
