Kent, Ohio, May 4 -- Four students at Kent State University, two of them women, were shot to death this afternoon by a volley of National Guard gunfire. At least 8 other students were wounded.

The burst of gunfire came about 20 minutes after the guardsmen broke up a noon rally on the Commons, a grassy campus gathering spot, by lobbing tear gas at a crowd of about 1,000 young people

In Washington, President Nixon deplored the deaths of the four students in the following statement:

"This should remind us all once again that when dissent turns to violence it invites tragedy. It is my hope that this tragic and unfortunate incident will strengthen the determination of all the nation's campuses, administrators, faculty and students alike to stand firmly for the right which exists in this country of peaceful dissent and just as strong against the resort to violence as a means of such expression."

the Assistant Adjutant General, said the troops had opened fire after they were shot at by a sniper.
