As the earliest stages of a massive assault on Gaza City take shape, Israel is calling up tens of thousands of reservists to take part in the impending military operation.

Israel's operations in Gaza City could begin within days, even as negotiators scramble to get Israel and Hamas to agree to end their 22 months of fighting.

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.

Israeli forces eliminated a Gaza terrorist involved in the Oct. 7 Kibbutz Nir Oz invasion and Yarden Bibas kidnapping during an Aug. 10 airstrike, the IDF and Shin Bet announced.

Troops have reached the city’s outskirts, an Israeli official said, adding that more reservists are being asked to report for duty to cover for other soldiers who will be involved in going into Gaza City.

Last week, Israeli Prime Minister Benjamin Netanyahu shifted Israel’s stance and demanded the release of all 50 remaining hostages at once. The move coincided with Netanyahu’s declaration that Israel intends to occupy Gaza City and other areas of the territory in an effort to ratchet up pressure on the group.
