(CNN) -- A lone gunman is dead after police said he killed at least 21 people Monday during twin shootings on the Virginia Tech campus -- the worst school shooting incident in U.S. history.

"Some victims were shot in a classroom," university police Chief Wendell Flinchum said during a news conference in Blacksburg.

Police believe there was only one gunman, Flinchum said.

"Today the university was struck with a tragedy that we consider of monumental proportions," said university President Charles Steger. "The university is shocked and indeed horrified."

The shootings mark the deadliest school shooting incident in U.S. history, topping attacks at Columbine High School in 1999 and at the University of Texas in 1966.

The Associated Press quoted officials saying more than 20 people were wounded. A hospital spokeswoman told AP that 17 Virginia Tech students were being treated for gunshot wounds and other injuries. the rest
