British Prime Minister Tony Blair says Britain is saddened by U.S. campus shooting rampage. United Nations Secretary-General Ban Ki-Moon also condemned the shooting spree. British Prime Minister Tony Blair expressed Britain's profound sadness on Tuesday (April 17) over the worst shooting rampage in U.S. history at Virginia Tech University on Monday. "Like everyone I am deeply shocked at the terrible loss of innocent lives at Virginia Tech University," he told a news conference at his Downing Street residence. " I would like to express, on behalf of Britain and the British people, our profound sadness at what has happened and to sent the American people, and most especially of course the families of the victims, our sympathy and our prayers." Later, U.N. Secretary-General Ban Ki-Moon also condemned Monday's shooting spree. "On this very tragic accident, I feel very much sorry and troubled, and any such rampant killing of innocent citizens and children is totally not acceptable and I condemn it in the strongest terms possible," said Ban. The gunman was identified today as Cho Seung-Hui, 23, an English literature student originally from South Korea who had been living in the United States legally with his parents for 14 years, a U.S. immigration official said. Cho killed himself at Virginia Tech after opening fire in four classrooms where in some cases he apparently chained doors to prevent victims from escaping, officials said. Two people at the University were shot to death two hours earlier at a campus dormitory.
