Israeli strikes killed and wounded dozens in Gaza's al-Shati refugee camp on Tuesday morning, amid the issuance of further expulsion orders to residents of Gaza City.
The latest atrocities come as Israel pushes ahead with its aim of invading and fully occupying Gaza City, while expelling the area's residents southwards.
It comes as talks aimed at putting a pause to the war on Gaza falter, with fears of mass casualties from the new offensive on Gaza City.
'Leave now'
Early on Monday, Gaza City residents received messages from the Israeli army urging them to "evacuate immediately via Al-Rashid road to the humanitarian area in Al-Mawasi" - a designated "safe zone" in Gaza, which has come under attack by Israeli forces.
"Remaining in the area is extremely dangerous," the message continued, echoing previous Israeli warnings that all who refuse to be displaced will be considered combatants.
Days earlier, Israeli forces began destroying high-rise residential blocks in the city, displacing hundreds of families from their homes.
On Monday, Israel bombed the Al-Salam Tower in the centre of Gaza City, as well as the 14-storey Vision Tower west of the city.
Israeli Defence Minister Israel Katz vowed to destroy more high-rise residential buildings, while Prime Minister Benjamin Netanyahu boasted that Israel had destroyed 50 residential buildings in two days, ordering Palestinians to "leave now".
Hamas slammed Netanyahu's remarks on the destruction of homes as the "most heinous images of sadism and criminality". The group also slammed the "impotence" of UN institutions to stop Israel's genocide.
Ceasefire talks 'faltering'
Despite optimism expressed by US President Donald Trump on Sunday that a deal to end the war would be achieved, Israeli media reported on Monday that the negotiations were likely to reach another deadlock.
Citing an unnamed Arab diplomatic source, The Times of Israel reported that Hamas would be unlikely to accept Israel's refusal to rule out resuming attacks on Gaza after a truce is achieved.
The current proposal pushed by Washington would see Hamas release all 48 remaining Israeli captives on the first day of the ceasefire, in exchange for the release of thousands of Palestinian detainees and a US guarantee that Israel would not resume its attacks.
Hamas has reportedly pushed back against this, expressing distrust of Washington's guarantees, particularly as it backed Israel's move to break the last ceasefire in March.
The Palestinian group has previously floated the possibility of UN sanctions on Israel if it resumes attacks on Gaza during a ceasefire.
On Monday, Qatar's Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al-Thani pressed Hamas political leaders to "respond positively" to the latest US-backed proposal, an official briefed on the talks told Reuters.
"The Qatari prime minister pressed Hamas to respond positively to the latest American proposal, conveyed through mediators, and aimed at securing a ceasefire and hostage release deal in Gaza," the official said.
