The proposal, made last week, follows an escalation in violence after Israel resumed air and ground operations against Hamas militants on March 18, ending a two-month period of relative calm after 15 months of war.
Gaza health officials said Israeli airstrikes and shelling have killed nearly 700 Palestinians since then, including at least 400 women and children.
Among those killed on Monday were two local journalists, Mohammad Mansour and Hussam Shabat, medics said. The Palestinian Journalist Syndicate said at least 206 journalists have been killed by Israeli fire in Gaza since early October 2023, when the conflict erupted. There was no immediate Israeli comment.
Islamist group Hamas said several of its senior political and security officials had also been killed.
Later on Monday, the Israeli military said it had intercepted a missile launched from Yemen before it crossed into Israel. Warning sirens had sounded in Jerusalem, Tel Aviv and other areas. Iran-aligned Houthi forces in Yemen have at times fired missiles at Israel in support of Hamas fighters.
The Egyptian plan calls for Hamas to release five Israeli hostages each week, with Israel implementing the second phase of the ceasefire after the first week, two security sources said.
Hamas is still holding 59 hostages, with 24 thought to be still alive, among the more than 250 it seized in its October 7, 2023 cross-border attack on Israel. Most of the rest have been freed, or their bodies handed over, in negotiated exchanges.
Both the U.S. and Hamas have agreed to the proposal, the security sources said, but Israel has not yet responded.
A Hamas official did not confirm the proposed offer, but told Reuters that "several proposals are being discussed with the mediators to bridge the gap and to resume negotiations to reach common ground that would pave the way to start the second phase of the agreement".
TIMETABLE FOR WITHDRAWAL
The sources said the Egyptian proposal includes a timeline for a full Israeli military withdrawal from Gaza, backed by U.S. guarantees, in exchange for the release of remaining hostages.
Hamas has accused Israel of breaking the terms of the January ceasefire agreement but has said it is willing to negotiate a renewed truce and was studying proposals from U.S. President Donald Trump's special envoy, Steve Witkoff.
Israel says it resumed its military operations to force Hamas to release the remaining hostages it is holding in Gaza.
On Monday, Hamas released a video it said showed hostages Elkana Bohbot, 35, and Yosef Haim-Ohana, 24, who were both abducted from the Nova music festival site on October 7.
Israel says it does its best to reduce harm to civilians and has questioned the death toll provided by health authorities in the Hamas-run enclave.
Palestinian officials on Sunday put the number of dead from nearly 18 months of conflict at over 50,000.

In Gaza's southernmost city Rafah, the municipality said thousands of people were stuck inside the Tel Al-Sultan district where some Israeli military forces had entered, with families trapped among the ruins, with no water, food, or medicine.
The Palestinian Civil Emergency Service said 50,000 residents remained cornered in Rafah, which abuts the border with Egypt.
The Israeli military said troops had encircled Tel Al-Sultan to dismantle "terror infrastructure sites and eliminate terrorists in the area".
A United Nations spokesperson said on Monday it would reduce its footprint in Gaza after five staff members of its Palestinian relief agency UNRWA were killed in the renewed conflict, but remains committed to providing aid to civilians.
Separately, UNRWA said 124,000 Palestinians have been displaced in Gaza in recent days.
"Families carry what little they have with no shelter, no safety, and nowhere left to go. The Israeli authorities have cut off all aid. Food is scarce and prices are soaring. This is a humanitarian catastrophe. The siege must end," UNRWA said on X.
Israeli forces strike Red Cross office in Gaza
Meanwhile, the Israeli military said its forces had fired on Monday at a building belonging to the Red Cross in Gaza's southern city of Rafah as a result of incorrect identification, after an office belonging to the aid organisation was damaged by an explosive projectile.
The International Committee of the Red Cross said no one had been injured, but that the attack had had a direct impact on its ability to operate.
The Israeli military said its forces had fired at the building after identifying suspects and sensing a threat. After examination, it turned out the identification was incorrect.
"The structure's ownership was unknown to the force at the time of the shooting," the statement added.
The ICRC did not blame any party but said it "strongly decries the attack against its premises".
The Israeli military said the incident would be investigated.
