A Jewish group demanding a ceasefire to stop Israel’s aggression in Gaza held protests on Thursday in eight US cities on the eighth night of Hanukkah, blocking rush-hour traffic on busy streets and bridges in Washington and Philadelphia, Reuters reports.

In Washington, the group Jewish Voice for Peace said about 90 protesters blocked the overpass to New York Avenue in the northwestern part of the US capital. Police said the demonstration closed the intersection of New York Avenue and North Capitol Street and urged people to use alternate routes.

“On the 8th night of Hanukkah, 8 cities, 8 bridges,” Jewish Voice for Peace said on X.

“We are here, gathering across the country in massive, growing numbers, to say no more.” Demonstrations also occurred in Boston, Atlanta, Chicago, Minneapolis, Seattle and Portland, Oregon.

In Philadelphia, about 200 protesters briefly blocked the I-76 highway, and more than 30 arrests were made, a Reuters witness said. Protesters held signs and banners that read: “Let Gaza Live” and “Not in our name.”
