US President George W Bush led thousands of teary-eyed students and staff of Virginia Tech University at a memorial service in the campus to mourn the loss of lives on "a day of sadness for the entire nation".
"Laura and I have come to Blacksburg with hearts full of sorrow. This is a day of mourning for the Virginia Tech community, and it is a day of sadness for our entire nation," Bush told a jam-packed auditorium on Tuesday in the campus where the memorial service was held.
"I came here to express sympathy...In this time of anguish, I hope you know that people all over this country are thinking about you and asking God to provide comfort for all who have been affected," Bush told a huge gathering of students who were sporting the school's burnt orange and maroon colours to honour those slain.
The President in very brief remarks stressed that it was impossible to make sense out of such suffering and violence especially against those people who really did not deserve it or just happened to be at the wrong place at the wrong time.
"Tuesday began like any other day: Students woke up and they grabbed their backpacks and they headed for class. And soon the day took a dark turn, with students and faculty barricading themselves in classrooms and dormitories, confused, terrified and deeply worried," said the president.
"It's impossible to make sense of such violence and suffering. Those whose lives were taken did nothing to deserve their fate. They were simply in the wrong place at the wrong time. Now they're gone, and they leave behind grieving families and grieving classmates and a grieving nation."
