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

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 has targeted militants and others who approach its troops, as President Trump’s deal faces new challenges.

Middle East envoy Steve Witkoff and Jared Kushner met with Prime Minister Benjamin Netanyahu, according to an Israeli government spokeswoman, and Vice President JD Vance is expected in Israel on Tuesday.

President Trump and Israel said the Gaza ceasefire is still in effect after an exchange of fire with Hamas this past weekend.

According to the terms of a cease-fire brokered by international mediators last week, Israel and Hamas would stop fighting and the militant group would return all the hostages it held — both living captives and the bodies of those who had died, totaling 48 people — in exchange for the freeing of Palestinians held by Israel, among other provisions.

Gaza's fragile ceasefire faced its first major test Sunday as Israeli forces launched a wave of deadly strikes, saying Hamas militants had killed two soldiers, and an Israeli security official said the transfer of aid into the territory was halted.
