Police in Oregon responding to elementary school shooting

A shooter opened fire at an elementary school in Bend, Oregon in the US and was ⁠promptly shot dead, and at least two people were taken away by ambulance, officials said.

"We don't have confirmation yet who shot the suspect. It may have been a bystander. At this time, we have multiple victims," said Sheila Miller, a spokesperson at the Bend Police Department, in a press conference.

The Bend-La Pine School District said in a statement on social media that the Silver Rail Elementary School was under lockdown.

An updated post later said law enforcement was escorting students in buses to a separate location, where families could reunite with their children.

Ms Miller said that officers were alerted to respond to a critical scene at 1pm local time, and that police were on the scene approximately two minutes later.

"Seconds later, we received word over the radio that the suspect in this incident was down," she said.

Ms Miller said medics had taken at least two people to a local hospital, adding that "we do not know their status".

The school is more than 160 kilometres southeast of the city Portland.

It serves grades kindergarten through to fifth grade, roughly ages five to 11.

It has about 450 students and 40 staff members, Ms Miller said.

There have been more than 360 mass shootings in the United States so far this year, according to the Gun Violence Archive, which defines a mass shooting as four or more people shot
