SAN JUAN, Puerto Rico (AP) -- About 300 students invaded a library and
                  protested outside a Reserve Officers Training Corps building Wednesday as
                  anger toward the U.S. military swelled at the University of Puerto Rico.

                  "Go to Hell, Navy!" students shouted. They pounded drums and waved
                  banners calling for the military to abandon a controversial training ground on
                  the outlying island of Vieques. Others called for the United States to stop
                  army recruiting efforts at colleges and to free 16 Puerto Rican nationalists
                  jailed some 20 years ago for sedition connected to more than 130 bombing
                  attacks on the U.S. mainland that killed six people.

                  Students also urged support for former University of Puerto Rico professor
                  Jose Solis Jordan, who was sentenced in July to 51 months in prison for
                  bombing a U.S. Army recruiting center in Chicago.

                  "They (military) should leave our campus, leave our Vieques, and leave our
                  country," Carlos Ivan Vargas, a spokesman for the Puerto Rican
                  Independence Party's youth branch, shouted to cheers.

                  Anti-American protests have flared in this U.S. territory following recent
                  accidents at the training ground and controversy over President Bill Clinton's
                  offer to free the 16 prisoners if they renounce violence. The prisoners,
                  members of two guerrilla groups, have not responded to Clinton's overture.

                  On Sunday, thousands of demonstrators marched in San Juan to demand
                  Clinton give the prisoners an unconditional pardon.

                  Wednesday procession wound past an anti-military mural and through the
                  library, where a sign urged helplessly, "Please keep the silence." It ended at
                  the building outside the campus where the ROTC was forced to relocate
                  following a 1971 riot over its presence that left three people dead.

                  Since the riot, activists have continued efforts to expel the ROTC from the
                  university.

                  "This movement of the people is giving people a sense that victory is close,
                  and that we may finally get them out," said Kevin Rivera, president of the
                  General Student Council, at Wednesday's rally.

                  Not all on campus agreed. "We're supposed to be part of the United States,
                  so (the military) has a right to be here," said Carlos Fonseca of Bayamon, an
                  accounting major, as he watched the march.

                  The ROTC said last year its membership had dropped from 600 to less than
                  180 since 1995. The corps' offices were closed because of the rally
                  Wednesday, and officials could not be reached for comment.
