DEIR AL-BALAH, Gaza Strip (AP) — Malnutrition rates among children in the Gaza Strip have doubled since Israel imposed sharp restrictions on the entry of food in March, the U.N. said Tuesday. New Israeli strikes killed more than 90 Palestinians, including dozens of women and children, according to health officials.

Hunger has been rising among Gaza’s more than 2 million Palestinians since Israel broke a ceasefire in March to resume the war and banned all food and other supplies from entering Gaza, saying it aimed to pressure Hamas to release hostages. It slightly eased the blockade in late May, allowing in a trickle of aid.

UNRWA, the main U.N. agency caring for Palestinians in Gaza, said it had screened nearly 16,000 children underage 5 at its clinics in June and found 10.2% of them were acutely malnourished. By comparison, in March, 5.5% of the nearly 15,000 children it screened were malnourished.

One strike in the northern Shati refugee camp killed a 68-year-old Hamas member of the Palestinian legislature, as well as a man and a woman and their six children who were sheltering in the same building, according to officials from the heavily damaged Shifa Hospital, where the casualties were taken.

One of the deadliest strikes hit a house in Gaza City’s Tel al-Hawa district on Monday evening and killed 19 members of the family living inside, according to Shifa Hospital. The dead included eight women and six children. A strike on a tent housing displaced people in the same district killed a man and a woman and their two children.

There was no immediate comment from the Israeli military on the strikes.
