Susan Sarandon, Hannah Einbinder among more than 100 detained during anti-Netanyahu protest outside UN

Meanwhile, protesters can be heard chanting with many wearing shirts that say, “Fund people not bombs,” and holding signs that say “Stop arming Israel” and “End the genocide.”

Comedian Caleb Hearon, author Glennon Doyle, New York congressional candidate Darializa Avila Chevalier, and former Army intelligence analyst Chelsea Manning were also among those detained, according to Jewish Voice for Peace, a human rights organization that advocates for Palestinian rights and held the protest.

Actor Susan Sarandon takes part in a protest Thursday ahead of Israeli Prime Minister Benjamin Netanyahu's address to the United Nations 81st General Assembly in New York City.

Other celebrities seen at the demonstration were actress and political activist Cynthia Nixon, playwright Tony Kushner, photographer Nan Goldin, and poet Eileen Myles. Congressional candidate Brad Lander also participated.

Jewish Voice for Peace said it held the sit-in outside the UN to “call on the world to stop arming Israel and to end the genocide in Gaza.”

A CNN team on the ground saw a heavy police presence with demonstrators remaining peaceful, but blocking traffic.

NYPD officers were seen arriving after 12 p.m. and warned demonstrators to clear the street. Around 30 people remained sitting and standing on the street, the CNN team saw.
