Massacre at Virgina Tech today as a student came to class with two guns and killed 22 students and injured 29 people at least.
Our thoughts and prayers are with all.
(CNN) -- The Virginia Tech Police Chief said at least 20 people were killed in twin shootings on the Blacksburg campus Monday morning.
"Some victims were shot in a classroom," Chief Wendell Flinchum said, adding that the gunman was dead.
President Charles Steger called the shootings "a tragedy of monumental proportions."
A hospital spokeswoman told The Associated Press that 17 Virginia Tech students were being treated for gunshot wounds and other injuries. Sharon Honaker at the Carilion New River Valley Medical Center told CNN that four patients had been transported there, one in critical condition.
One person was killed and others were wounded at multiple locations inside a dormitory about 7:15 a.m., Flinchum said. Two hours later, another shooting at Norris Hall, an engineering building, resulted in multiple casualties, the university reported. (Watch police, ambulances hustle to the scene Video)
The first reported shooting occurred at West Ambler Johnston Hall, a co-ed dormitory that houses 895 students. The dormitory, one of the largest residence halls on the 2,600-acre campus, is located near the drill field and stadium.
Amie Steele, editor-in-chief of the campus newspaper, said one of her reporters at the dormitory reported "mass chaos."
The reporter said there were "lots of students running around, going crazy, and the police officers were trying to settle everyone down and keep everything under control," according to Steele.
