Israeli air strikes killed at least 27 Palestinians across Gaza on Saturday, local rescue officials said. The Hamas-run civil defence agency reported that women and children were among the dead. In one attack, helicopter gunships hit a tent sheltering displaced people in Khan Younis, southern Gaza. Palestinians called these the heaviest strikes since the new ceasefire started earlier this month. The Israeli military said the strikes were in response to Hamas violating the ceasefire on Friday. According to the Israel Defense Forces (IDF), "eight terrorists were identified exiting the underground terror infrastructure in eastern Rafah." The IDF, with the Israel Security Agency, hit several targets including "four commanders and additional terrorists," weapons storage and manufacturing sites, and two Hamas launch sites in central Gaza. Hamas condemned the strikes and asked the US to act immediately. It said, "these ongoing violations confirm that the Israeli government continues its brutal war of genocide against the strip." Seven victims were from a displaced family in Khan Younis. The strikes also hit residential apartments, tents, shelters, and a police station. At Gaza City's Shifa hospital, officials said an air strike hit a residential apartment, killing three children and two women. Samer al-Atbash, uncle of the dead children, said, "We found my three little nieces in the street. They say 'ceasefire' and all. What did those children do? What did we do?" Video from Gaza showed bodies being pulled from rubble and buildings destroyed. The current conflict started after Hamas attacked southern Israel on 7 October 2023, killing around 1,200 people and taking 251 hostages. Israel responded with a military campaign in Gaza, killing over 71,660 people, according to Hamas health ministry figures. At least 509 Palestinians have died since the ceasefire on 10 October 2025, along with four Israeli soldiers. Though Israel had disputed casualties earlier, a senior security source told local media the military accepts more than 70,000 Palestinians were killed. The UN and rights groups consider the Hamas health figures reliable. Israel does not allow independent media into Gaza. These strikes come just before the Rafah border crossing with Egypt reopens on Sunday, following the recovery of Israel's last hostage's body earlier this week.
