Student protesters hunker down as more unrest rocks U.S. campuses
NEW YORK — Students who occupied a Columbia University building vowed Tuesday to fight back against efforts to evict them, as administrators struggled to contain pro-Palestinian protests that have launched dozens of campus demonstrations around the United States.
The demonstrations — the most sweeping and prolonged unrest to rock U.S. college campuses since the Vietnam war protests of the 1960s and 70s — have led to several hundred arrests of students and other activists.
Many of them have vowed to maintain their actions despite suspensions and threats of expulsion.
