"Active shooter" at US University
Ohio State University has told students that there is an active shooter on campus, and that they should "Run Hide Fight".
Seven people have been sent to hospital. Two are stable with no further details on the other five.
Ohio State's official Twitter page retweeted a post from OSU Emergency Management saying there is an active shooter on campus in Columbus.
The tweet said: "Buckeye Alert: Active Shooter on campus. Run Hide Fight. Watts Hall. 19th and College."
Watts Hall is a materials science and engineering building.
"Run. Hide. Fight" is standard protocol for active shooter situations. It means: Run, evacuate if possible; Hide, get silently out of view; or Fight, as a last resort, take action to disrupt or incapacitate the shooter if your life is in imminent danger.
A Columbus police dispatcher declined to comment on the reports, but police vehicles were seen at the scene.
With nearly 60,000 students at its main Columbus campus, Ohio State is one of the nation's largest universities.
