With the cease-fire deal under strain, Vice President JD Vance is set to meet with Prime Minister Benjamin Netanyahu and other leaders.

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

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

The group still commands thousands of fighters, but the war has taken a toll on its weapons supplies and its political future is uncertain.

The vice president is in Israel as questions remain over the long-term plan for peace, such as whether Hamas will disarm and who will govern Gaza.

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.

The Israeli military announced it resumed enforcing the ceasefire late Sunday. Aid deliveries will resume Monday through multiple crossings after Israeli inspection, in line with the agreement, according to an Israeli security official.
