Israel and the U.S. say the new system is aimed at preventing Hamas from siphoning off assistance. Israel has not provided evidence of systematic diversion, and the U.N. denies it has occurred.U.N. agencies and major aid groups say the new system allows Israel to control who receives aid and forces people to relocate to distribution sites, risking yet more mass displacement in the coastal territory.

“It’s essentially engineered scarcity,” Jonathan Whittall, interim head in Gaza of the U.N. humanitarian office, said last week.after Israel slightly eased its nearly three-month blockade of the territory last month. The groups say Israeli restrictions, the breakdown of law and order and widespread looting make it extremely difficult to deliver aid to Gaza’s roughly 2 million Palestinians.Experts have warned that the territory

if more aid is not brought in.The war began when Hamas-led militants stormed into southern Israel on Oct. 7, 2023, killing some 1,200 people, mostly civilians, and abducting 251. They are still holding 58 hostages, around a third believed to be alive, after most of the rest were released in ceasefire agreements or other deals.

Israel’s military campaign has killed over 54,000 people in Hamas-run Gaza, mostly women and children, according to Gaza’s Health Ministry, which does not say how many of the dead were civilians or combatants. The offensive has destroyed vast areas, displaced around 90% of the population and left people almost completely reliant on international aid.

appeared to stumble Saturday when Hamas said it had sought amendments to a U.S. ceasefire proposal that Israel had approved, and the U.S. envoy called that “unacceptable.”Sleep deprivation is linked to heart disease, cognitive decline, obesity and numerous other problems. And that circadian clock affects more than sleep, also influencing things like heart rate, blood pressure, stress hormones and metabolism.

Fatal car crashes temporarily jump the first few days after the spring time change, according to a study of U.S. traffic fatalities. The risk was highest in the morning, and researchers attributed it to sleep deprivation.Then there’s the cardiac connection. The American Heart Association points to studies that suggest an uptick in heart attacks on the Monday after daylight saving time begins, and in strokes for two days afterward.

Doctors already know that heart attacks, especially severe ones, are a bit more common on Mondays generally — and in the morning, when blood is more clot-prone.Researchers don’t know why the time change would add to that Monday connection but it’s possible the abrupt circadian disruption exacerbates factors such as high blood pressure in people already at risk.
