Update -- 1:30 p.m.
A gunman armed with a rifle shot and killed a student Tuesday and injured a teacher shortly after classes started at a US school in Oregon. The alleged shooter was also found dead.
Authorities have tentatively identified the gunman but weren't ready to release the name, Troutdale Police Chief Scott Anderson said. Anderson said the teacher suffered non-life threatening injuries and was treated at the scene.
The attack panicked students, and a lockdown was ordered.
One student was fatally shot and the suspected gunman is dead in a US high school shooting that happened earlier today at Reynolds High School in Troutdale, Oregon.
The Multnomah County sheriff's office said there were reports of shots fired about 8 a.m. Tuesday.
Students say they were told over the intercom there was a lockdown and to quietly go to their classrooms.
Students were evacuated from the school, hands on their heads, to be reunited with their parents in a supermarket parking lot.
Daniel DeLong, 15, said while waiting after the shooting that he saw a physical education teacher at the school with a bloodied shirt.
"I'm a little shaken up," DeLong said. "I'm just worried."
Freshman Morgan Rose, 15, said she was hunkered down in a locker room with another student and two teachers.
"It was scary in the moment now knowing everything's OK I'm better," she said.
Special Weapons and Tactics teams were going through the school room by room, KGW-TV reported.
Police set up tape around the area and were not allowing people to pass through. Fire trucks were on the scene.
The shooting follows a spate of recent attacks at or near school campuses.
On June 5, a 19-year-old man was killed and two other people wounded when a gunman opened fire in a building at Seattle Pacific University. The 26-year-old suspect is being held without bail. Police said he had no connection to the university, but apparently was planning to kill as many people as he could before killing himself.
Gun control is a fiercely divisive issue in the United States, where the right to bear arms is enshrined in the Constitution, alongside such basic rights as free speech and freedom of religion.
President Barack Obama's plan for broader background checks on gun purchases, along with proposals for a ban on military-style assault rifles and limits on ammunition capacity, failed last year in Congress.
This despite the December 2012 killings of 20 children and six adults at an elementary school in Newtown, Connecticut, that shocked the nation.
