LOS ANGELES (Web Desk) – A gunman killed at least ten people in Oregon, law enforcement officials said Thursday.

The first 911 calls reported shooting at Umpqua Community College at 10:38 a.m., and several law enforcement agencies responded. Officials said there were multiple casualties, but they were not sure of a number, New York Times reported.

Ray Shoufler, a fire marshal with the Douglas County Fire Department told MSNBC that as many as seven to 10 people could be dead. Mr. Shoufler also said that a number of injured people had been taken to nearby hospitals.

Numerous law enforcement agencies responded to the shooting, he said.

He said that the campus remained on lockdown and that some of the outlying classroms were being evacuated.

The college is in Roseburg, in rural southwestern Oregon, has about 3,00 students, and is about three hours south of Portland.

A spokeswoman for the Oregon department that oversees community colleges in the state told The Associated Press that she had not received any detailed information about the shooting. “It’s extremely concerning and sad,” Endi Hartigan, spokeswoman for the Higher Education Coordinating Commission, said.
