The US military's Central Command "has confirmed that the Israeli army forces completed the first phase withdrawal to the yellow line at 12 PM local time," President Donald Trump's special envoy Steve Witkoff said on X.
"The 72-hour period to release the hostages has begun," Witkoff added.
On Thursday, US President Donald Trump said he expected to travel to the Middle East on Sunday to celebrate the first phase of the Gaza peace deal.
However, Israel's Channel 12 News reported Friday morning that new adjustments have been made to the timing and itinerary of Trump's anticipated visit to Israel.
The president was initially expected to arrive on Sunday night, but the channel, citing the White House, said the visit has been postponed to Monday.
The report attributed the change to "logistical difficulties in organising the visit on such short notice."
Trump's two special envoys, Steve Witkoff and Jared Kushner, held meetings with the Israeli president and prime minister in Jerusalem on Thursday, the Israeli leaders' offices said.
During their meeting with Isaac Herzog, the Israeli president "discussed with the envoys the framework of the agreement they led and negotiated to secure the return of the hostages and to bring about an end to the war with Hamas," the Israeli presidency said in a statement.
The two later met with Prime Minister Benjamin Netanyahu, his office said.
Israeli media reported that the two US envoys later participated in an ongoing government meeting held to approve the plan.
Speaking at the White House, Trump said the agreement between Israel and the Palestinian group had "ended the war in Gaza."
The US leader added that "nobody's going to be forced to leave" the Palestinian territory under his 20-point peace plan, which formed the basis for indirect negotiations between Hamas and Israel in Egypt.
He said he hoped to travel to Israel, where he may address parliament, and maybe to Egypt.
"The hostages will be coming back Monday or Tuesday. I'll probably be there, I hope to be there," Trump told reporters in the Oval Office.
But Trump said the bodies of some of the dead captives would be "hard to find."
