“I don’t believe in this war,” said Rosalind Petchesky, 81, a member of Jewish Voice for Peace who was later taken into custody by police.

Sumaya Awad said she wanted the U.S. government to “follow the guidance and the wants of the majority of Americans.”

“We’re here engaging in civil disobedience to make it clear that we want the bombs to stop falling,” she said.

The protest disrupted the evening commute for thousands of people on Friday evening. Commuters walked by, some pausing, others looking confused. No train delays were reported because of the protest.

The police tried unsuccessfully to block the entrances to Grand Central, then stood and watched as demonstrators took over the main concourse.

By 7 p.m., with hundreds of protesters still in the station, the police told people to leave and began taking hundreds of protesters into custody. Soon after, the Metropolitan Transportation Authority announced that it would not allow anyone to enter the terminal and designated two entryways as exits only.

A total of 335 people were taken into custody, according to the police on Saturday, and they were issued summonses for criminal trespass and disorderly conduct.

As the demonstration in the main concourse officially wound down, police officers used a lift to reach two protesters standing on a ledge above the ticket booths, in front of the departures board. They were holding a sign that said, in all capital letters, “Never again for anyone.”
