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

By Alexander Cornwell and Nidal al-Mughrabi KIRYAT GAT, Israel (Reuters) -The U.S. increased pressure on Hamas on Tuesday to disarm in the next phase of an already fragile Gaza ceasefire as President Donald Trump pushed to cement an end to the devastating conflict.

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 Trump peace plan calls for an international security force in the Gaza Strip, but countries that might send troops are wary of danger, an unclear mission and being seen as occupiers.

Trump said on Monday that the US would destroy Hamas if the militant group didn’t continue to honor the ceasefire with Israel.

Vice President JD Vance said that he's confident in "durable" peace amid the ceasefire, warning Hamas will be "obliterated" if it doesn't cooperate.

Israel has accused Hamas of attacking Israeli forces in southern Gaza with the military carrying out airstrikes in the city of Rafah, the first major test of the US-brokered ceasefire.
