Holding signs emblazoned with slogans like “Boycott Israeli Apartheid” and “New York Jews Say: Not in Our Name,” hundreds of protesters marched through lower Manhattan on Thursday demanding an end to American support for Israel’s operation in Gaza.

The event was one of many held in the U.S. and around the world as part of a “national day of action” against Israel’s Gaza campaign. Two Jewish groups, Jewish Voices for Peace and Jews Say No!, were among the march’s organizers, and numerous Jews came to protest Israel’s military campaign.
