Pro-Palestinian protesters have blocked several New York City bridges and a tunnel to demand an immediate ceasefire in the three-month-old Israel-Hamas fighting, Reuters reports.

Dozens of demonstrators sat in the roadway and chanted slogans while holding up traffic on the Brooklyn, Manhattan and Williamsburg bridges across the East River, as well as at the Holland Tunnel connecting New York City with New Jersey across the Hudson River, local media reported.

The Port Authority of New York and New Jersey, which operates the Holland Tunnel, said on its website that the lanes to New Jersey were closed “due to police activity.”

Video posted on social media showed protesters chanting: “NYPD, KKK, IDF theyre all the same,” referring to the New York Police Department, Ku Klux Klan and the Israel Defence Forces.

Protesters at the Holland Tunnel carried banners that said “Lift the siege on Gaza,” “Ceasefire Now” and “End the occupation.”

The protests were organised by Jewish Voice for Peace, the Palestinian Youth Movement and the New York chapter of the Democratic Socialists of America, among other groups, they said on X, formerly called Twitter.

“The siege on Gaza needs to end and I’m ready to put my body on the line to end it,” said one protester as she was led away by a police officer with her hands behind her back, video showed.
