DEIR AL-BALAH, Gaza Strip — Israeli strikes overnight and into Sunday killed 15 people in the Gaza Strip, mostly women and children, according to local health officials.

Two of the strikes hit tents in the southern city of Khan Younis, each killing two children and their parents, according to Nasser Hospital, which received the bodies. Another seven people were killed in strikes elsewhere, including a man and his child in a Gaza City neighborhood, according to hospitals and Gaza’s Health Ministry.

The Israeli military says it targets only militants and tries to avoid harming civilians. It blames Hamas for civilian deaths in the 19-month-old war because the militants are embedded in densely populated areas.

Israel has sealed Gaza off from all imports — including food, medicine and emergency shelter — for over 10 weeks in what it says is a pressure tactic aimed at forcing Hamas to release its hostages. Israel resumed its offensive in March, shattering a ceasefire that had facilitated the release of more than 30 hostages.

The U.N. and aid groups say food and other supplies are running low and hunger is widespread.

Children carrying empty bottles raced after a water tanker in a devastated area of northern Gaza on Sunday. Residents of the built-up Shati refugee camp said the water was brought by a charity from elsewhere in Gaza. Without it, they rely on wells that are salty and often polluted.

“I am forced to drink salty water. I have no choice,” Mahmoud Radwan said. “This causes intestinal disease, and there’s no medicine to treat it.”

COGAT, the Israeli military body in charge of Palestinian civilian affairs, says enough aid entered during a two-month ceasefire this year and that two of the three main water lines from Israel are still functioning. Aid groups say the humanitarian crisis is worse than at any time in the 19-month war.

U.S. President Donald Trump, whose administration has voiced full support for Israel’s actions, is set to visit Saudi Arabia, Qatar and the United Arab Emirates this week in a regional tour that will not include Israel.

The war began when Hamas-led militants attacked southern Israel on Oct. 7, 2023, killing some 1,200 people, mostly civilians, and taking 251 hostage. Fifty-nine hostages are still inside Gaza, around a third of them believed to be alive; most of the rest were released in ceasefire agreements or other deals.
