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.

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 has reopened two crossings in Gaza, while the key Rafah crossing will stay closed to the movement of people until further notice.

By Nidal al-Mughrabi and Steven Scheer CAIRO/JERUSALEM (Reuters) -Israeli fire killed three people near a ceasefire line in Gaza on Monday, medics said, with U.S. envoys expected in Israel to try to push forward the fragile truce that faced its gravest test so far over the weekend.

Special envoy Steve Witkoff and U.S. President Donald Trump's son-in-law Jared Kushner are in Israel Monday to shore up the tenuous ceasefire that's holding in Gaza.

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

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.

Israel and Hamas say they are committed to the ceasefire after clashes over the weekend. And, lawmakers not feeling the pressures of the government shutdown.
