Students returned to Columbia University for the first day of classes of the fall semester Tuesday.

While it’s a new semester for roughly 9,000 students at the university, many who showed up for classes faced scenes similar to the springtime pro-Palestinian protests that capped off a tumultuous end to the previous semester.

"I thought things were going to settle down, but now I don’t think so,” said Yang Zhoa, a graduate student attending Columbia.

"School is starting again,” said another student named Thomas. “There's some other stuff that's going on that's taking away from it a little bit, but trying to make the most of it.”

Tuesday's protests included the arrest of at least one student outside an entrance to the university’s campus.

It wasn’t immediately clear how many of Tuesday's protesters were students, teachers or demonstrators with no ties to the Ivy League school. Their demands remained the same.

“We want Columbia's administration to know we are not letting up,” said PhD student Linnea Norton. “We will not stop until they disclose their financial investments into companies profiting off of the genocide in Gaza and weapons manufacturers.”

The protests come a few weeks after the previous university president resigned following her handling of the spring semester protests and the arrest of pro-Palestinian demonstrators. The university has since tightened campus security. Access is now restricted to students, faculty and staff with Columbia IDs. Guests must fill out an online form.

A recent 90-page report released by the administration detailed accounts of discrimination and antisemitism from hundreds of Jewish students on campus.

Jewish students enrolled for the fall semester are hoping this year will be different.

"It seems like sentiments are shifting,” said David Lederer, a Jewish Columbia University student. “People just want to go to class. We want to just have a normal college experience.”

NY1 reached out to Columbia University to ask whether the university requested the NYPD's help, a move that sparked criticism in the spring.

NY1 also reached out to the NYPD but has not yet heard back.

Meanwhile, in response to the school's antisemitism report, Columbia’s interim president, Katrina Armstrong, said discrimination has no place on campus.

The report laid out recommendations such as anti-bias training, and workshops on antisemitism and Islamophobia.
