Dozens of people were killed in Gaza, officials said Saturday, as protestors in Israel demand an end to the war in the Palestinian enclave and release of the remaining Hamas-held hostages.

The drums of war are pounding on the doorstep of Gaza City. Residents of the largest city in northern Gaza, packed with locals and refugees, fear the hours are ticking down before a looming Israeli offensive.

Israeli Defense Minister Israel Katz warned that Gaza city could "turn into Rafah and Beit Hanoun" unless Hamas agrees to Israel's terms.

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.

An Israeli military spokesman says troops will deepen the damage to the "terror infrastructure" held by Hamas.

Israeli Prime Minister Benjamin Netanyahu says he has ordered negotiations for the release of all hostages and an end to the war in Gaza “on terms acceptable to Israel.”

"Soon the gates of hell will open upon the heads of Hamas murderers and rapists in Gaza—until they agree to Israel's conditions for ending the war, foremost among them the release of all hostages and the dismantling of their weapons," Katz said in his post, which was originally in Hebrew.

Turkey's first lady has urged Melania Trump to confront Benjamin Netanyahu over the need to protect children during times of war. It comes as medics inside Gaza say at least 25 Palestinians have been killed today.
