Israeli strikes killed dozens of Palestinians across Gaza on Thursday and early on Friday, with the Palestinian Civil Defence saying at least 28 were killed in two separate strikes.
Airstrikes on a home in Gaza City's al-Daraj neighbourhood killed at least seven people and left several others wounded, while strikes on the Abu al-Hatl and Ziyada families, also in Gaza City, killed at least six people.
In the West Bank, an Israeli assault on the town of Qabatiya, south of Jenin, killed at least 7 people and wounded 11 others.
Video has emerged from the attack showing Israeli soldiers pushing the bodies of Palestinians from the rooftops of buildings.
Israeli forces have also continued to escalate attacks on Lebanon, where Hezbollah leader Hassan Nasrallah vowed to continue the confrontation with Israel.
Meanwhile, Washington has denied that the ceasefire talks were collapsing, with the Pentagon reiterating that a deal would lower the temperature across the region.
