Pro-Palestinian protesters halted traffic in NYC on Sunday afternoon by descending at the foot of the Manhattan Bridge and demanding a cease-fire between Israel and Hamas — even though there has been a cease-fire since Friday.

A number of arrests were made as hundreds of protesters sat down on the heavily trafficked East River overpass and held their fists in the air while shouting “Let Gaza Live” and wearing shirts that read “Cease Fire Now.”

They called for President Joe Biden to end his support of Israel’s military campaign.

“Business as usual cannot continue, as thousands of Palestinians are trapped under the rubble,” Jay Saper, of the protest-organizing Jewish Voice for Peace, told The Post.

“We’ve gathered to raise our voices for a permanent and lasting cease-fire. The majority of Americans are with us, polling shows that.

“We’re elevating the voices of New Yorkers who are calling for a cease-fire.”

The demonstrators demanded that the US halt its military support for Israel, and pressure the leaders of the Jewish state to end its assault on Gaza.

“We don’t believe there is a military solution,” Saper said. “We believe the causes of violence are oppression. We first need to address 75 years of Israeli apartheid. Sixteen years of suffering and blockade against the people of Gaza.”

Three demonstrators — one woman and two men — were arrested during the protest, according to law enforcement sources.

One protester could be seen spray painting “Gaza” on a support beam of the bridge.

Despite the organizers’ claim of widespread support, everyday New Yorkers were furious that the traffic blockade was throwing a wrench in their travel plans.

“Oh hell no — I have to get across the bridge!” Pam Allen, a fashion model on her way to a show in Brooklyn, told The Post. “I’m all for peace, but this right here, this is a problem.”

She continued: “I get it, I understand the message — but this solves nothing!”

One person who was driving a commercial van became aggravated that the protesters ruined his commute.

“I’m just trying to get home after working all night!” he told The Post. “This makes me mad. How do I get home?”

In Hicksville, Long Island hundreds of protesters gathered outside a Dunkin’ Donuts and marched past the offices of defense contractor Northrop Grumman to protest military action in Gaza.

Noura Farouk from the organization “Mothers For Justice” addressed the gathering with a megaphone while standing on the back of a pickup truck.

Farouk emphasized that the overwhelming number of fatalities in Gaza were women and children.

“Children have been orphaned in the blink of an eye. There’s no politics that justifies this.” Farouk said.

“All mothers and parents should be aware that 50 percent of Gaza is children.”

As policeman on horseback helped direct traffic, demonstrators chanted “Northrop Grumman to you can’t hide — we charge you with Genocide.”

According to protester Rosy Islam, the choice to target the defense giant’s Long Island headquarters was “symbolic.”

“I think that dialogue is what’s needed right now. We don’t want our tax dollars to be going outside the U.S.” Islam told The Post outside the Grumman headquarters.

“We should help our own people here in our neighborhood, in our own community.”

Islam said she wanted to “let Long Islanders know that we’re all here to stand for humanity.”

Yitzak Deutsch, a member of New York’s Orthodox Jewish community, protested in solidarity with Palestinians.

“We are here because we are Jews–because we are true to our religion. We are here to say that what the occupation stands for is totally wrong,” Deutsch told The Post as marchers dispersed.

“It’s totally criminal. They use my religion in order to justify the crimes which is totally wrong. Judaism is a religion—Zionism is a political movement. And, of course this genocide and all the atrocities is nothing my name and my religion.”
