Medics said an Israeli airstrike on Monday killed a woman in the town of Zawayda in the central Gaza Strip, while another strike killed one person in the nearby Nuseirat refugee camp.
Later on Monday, an Israeli airstrike targeted the rooftop of a building in Gaza City, killing two people, a medic and his son, health officials said.
The Israeli military said it killed two Hamas militants in separate strikes in the Gaza Strip. It said the militants were planning to carry out attacks against Israeli troops, without providing further details.
The violence comes as Nikolay Mladenov, US President Donald Trump's Board of Peace envoy for Gaza, was expected to arrive in Cairo later on Monday, sources close to the mediation effort said, a day after Hamas delivered its response to a 15-point blueprint he had presented to them in recent weeks.
The sources said Hamas and other factions had agreed on all the points except Hamas disarmament, which the group links to Israeli withdrawal and a political track to negotiate Palestinian statehood.
An October 2025 truce brokered by Trump has failed to halt Israeli attacks in Gaza or to secure the disarmament of Hamas militants.
Israel and Hamas remain deadlocked over how to proceed with the next stage of Trump's Gaza plan, which involves Hamas laying down its arms and Israeli withdrawals.
Hamas on Monday said leaders of Palestinian factions who held discussions with mediators — Egypt, Qatar and Turkey — over the past week in Cairo had stressed the need for Israel to "fully and unconditionally comply with the terms of the ceasefire agreement, in its entirety and without fragmentation".
Hamas blames the absence of a full agreement to end the Gaza conflict on Israel's refusal to fulfil first-phase obligations agreed in October, which halted major fighting but did not end Israeli attacks. Israel says its strikes are intended to thwart imminent attacks by Hamas and other militants.
Israeli strikes in Gaza have killed more than 990 people since the truce, health officials say, while Israel says four soldiers have been killed by militants in that period.
Israel insists Hamas must disarm, cede power in Gaza and play no role in the future of the enclave.
Israel still occupies more than half of Gaza, where it has ordered residents out and demolished remaining structures.
Nearly the entire population of more than two million Palestinians now lives in a narrow strip along the coast, mainly in tents and damaged buildings, under Hamas' de facto control.
