Medics said an Israeli airstrike killed at least four people and wounded three others, including children, in a tent in the western area of Khan Younis in the southern Gaza Strip. Another strike killed a person east of the city, near where Israeli forces operate.
Later on Thursday, medics said a man was killed in an Israeli strike at a school, which also housed displaced families in Jabalia north of the enclave, while another strike killed another person in a tent near Deir Al-Balah in the central Gaza Strip, taking Thursday's death toll to at least seven.
There was no immediate Israeli comment on the reported deaths.
Earlier, the military said it had struck a launch site shortly after the firing of a rocket that had failed to reach Israeli territory. It accused Hamas of violating the ceasefire twice in the past 24 hours. A source from the Palestinian militant group told Reuters it was checking the allegation.
A ceasefire agreed in October has not progressed beyond the first phase, under which major fighting stopped, Israel withdrew from less than half of Gaza and Hamas fighters released live hostages and human remains in return for detained Palestinians.
Under future phases yet to be hammered out, US President Donald Trump's plan envisages Hamas disarming, Israel pulling out further and an internationally backed administration rebuilding Gaza.
But little progress has been made on the next steps. More than 400 Palestinians and three Israeli soldiers have been reported killed since the ceasefire took effect, and nearly all of Gaza's more than two million people now live in makeshift homes or damaged buildings in a sliver of territory where Israeli troops have withdrawn and Hamas has reasserted control.
Israel is awaiting the handover of the final body due under the initial stage of the truce. An Israeli official close to Prime Minister Benjamin Netanyahu has said Israel would not move to the next phase of the ceasefire until Hamas returns the remains of the last Israeli hostage still held in Gaza.
Israel has yet to open the Rafah crossing between Gaza and Egypt, another condition of the US-backed plan, saying it will do so only once the remains are returned.
Israel and Hamas have accused each other of major breaches of the ceasefire deal and remain far apart on the more difficult steps envisaged for the next phase.
Israel has continued to carry out air strikes and targeted operations across Gaza. The Israeli military said it views "with utmost severity" any attempts by militant groups in Gaza to attack Israel.
A Hamas official told Reuters on Thursday the group had documented more than 1100 Israeli violations of the ceasefire since October and had urged mediators to intervene. The violations include killings, injuries, artillery and aerial strikes, home demolitions and detention of people, he said.
Hamas has refused to disarm and has been reasserting its control. Israel has said it will resume military action if Hamas is not disarmed peacefully.
Hamas-led militants killed some 1200 people and abducted 251 others in an assault on Israel on October 7, 2023, according to Israeli figures. More than 71,000 Palestinians have been killed in Israel's offensive in Gaza since then, according to the territory's health ministry.
