Scores of New York police officers entered Columbia University’s campus on Wednesday, a day after pro-Palestine student protesters barricaded and occupied a building inside the campus.Police officers, in tactical gear and helmets, marched into the campus and climbed up to the second floor of Hamilton Hall from a truck. On Tuesday, the protesters occupied Hamilton Hall and unfurled a banner reading “Hind’s Hall,” to pay tribute to a 6-year-old Palestinian child killed by the Israeli military.Officers have begun clearing the occupied building and arrested several protesters. Over 50 protesters have been detained so far, news agency Reuters said. The action comes after dozens of university campuses across the US have seen large-scale protests against Israel’s war in Gaza. The demonstrations have also led to arrests of students who have vowed to continue their protest despite threats of expulsion from university administrations.Hours before the police entered the campus, New York Mayor Eric Adams said the takeover of Hamilton Hall was instigated by “outside agitators” who have turned “peaceful protests into a violent spectacle”. “We cannot wait until this situation becomes even more serious. This must end now,
