President Donald Trump gave Hamas a 48-hour ultimatum to return bodies of 13 deceased hostages or face consequences from countries involved in the Gaza peace deal.

Earlier this month, Israel and Hamas announced a ceasefire to the two-year war in Gaza. The agreement was brokered in part by the United States, but American officials are concerned, according to the New York Times,

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

Military and Middle East experts say a new Gaza rebuilding plan focused on creating secure enclaves, restoring stability and cutting off Hamas terrorists could succeed in the long term.

Hamas has deployed hundreds of police and clashed with armed groups in Gaza in what the militant group says is an attempt to restore law and order in areas where Israeli troops have withdrawn for the U.

Israel said Sunday it responded after "terrorists" attacked troops operating in the Rafah area with gunfire and an anti-tank missile. Hamas said it was unaware of the clashes.

US Secretary of State insisted that the ceasefire is holding in place despite concerns over aid and recent clashes in Gaza

Secretary of State Rubio declared UNRWA won't assist Gaza aid delivery, calling the U.N. agency a "subsidiary of Hamas" amid the U.S.-brokered ceasefire.
