In a general student assembly yesterday, a majority of students of the main campus of the University of Puerto Rico voted in favor of ending the strike for one month [es], but they declared a one day walk out today as part of their protest initiatives against the imposition of a $800 annual fee. This morning tensions are high, once again, at Río Piedras with students trying to enter the campus [es] to take classes while others have barricaded the entrances.
