Protesters in Israel escalated their ongoing campaign on Sunday to secure the release of hostages held in Gaza.

The Hostages and Missing Families Forum, which organized the "Israel on Hold” protests, said that over a million people took part in the demonstrations across the country on Sunday. Per the organization, almost 500,000 protesters gathered in Tel Aviv’s Hostage Square.

Israel is studying Hamas' response to a proposal for a 60-day ceasefire and release of half the hostages still held in Gaza, two Israeli officials said, although one source reiterated that all Israeli captives must be freed for the war to end.
