An Israeli security official said the transfer of aid into the territory is halted "until further notice," the first major test of the ceasefire.

Israel said it had begun "renewed enforcement of the ceasefire" Sunday after launching strikes in Gaza as it traded accusations with Hamas that each side had violated the fragile truce.

A round of violence on Sunday was short-lived, but analysts expect more tensions between Israel and Palestinian militants that will put the truce under strain.

The Israeli military said on Sunday that a ceasefire in Gaza had resumed after an attack that killed two of its soldiers and prompted a wave of airstrikes that killed 26 people, in the most serious test yet of this month's U.

Having transformed an Israeli attack on Qatari soil into diplomatic momentum for a ceasefire in Gaza, officials in Doha are forging ahead on other thorny conflicts, including the escalating tensions between the United States and Venezuela.

Detainees seek to return to their normal lives in Gaza after being freed from Israeli captivity, where some say they faced torture and beatings.

Jared Kushner and U.S. Special Envoy Steve Witkoff spoke to CBS' "60 Minutes" about helping to negotiate the Gaza ceasefire deal between Israel and Hamas.

"If they are successful, Hamas will fail, and Gaza will not be a threat to Israel in the future," Kushner said. The U.S. peace deal, still in its first phase, saw Hamas release 20 living hostages, and so far return the bodies of at least 10 confirmed deceased hostages .
