The transition official told NBC that Indonesia, for instance, is among the locations under discussion for where some could go.

The network also revealed that Trump's envoy to the Middle East, Steve Witkoff, is considering visiting the Gaza Strip to preserve the ceasefire deal that went into effect on Sunday.

An official told NBC that Witkoff also plans to be a near-constant presence in the region over the coming weeks and months to troubleshoot flare-ups on the ground that he believes could unravel the agreement.

"You have to be right on top of it, ready to snuff out a problem if it happens," the official said.

For now, a top concern for Trump's envoy is a rogue incident sparked by inevitable day-to-day interfacing on the ground in and near Gaza, even given the ceasefire agreement.

"Remember, there's a lot of people, radicals, fanatics, not just from the Hamas side, from the right wing of the Israeli side, who are absolutely incentivized to blow this whole deal up," the official said.

The president-elect's envoy used Trump's history with Israel and his dynamic with Netanyahu to pressure the Israelis, the source said.

Witkoff met the Israeli prime minister on Saturday for a harsh exchange.

He told people privately that his words to Netanyahu that Saturday, 11 January, were not a threat and that one of Netanyahu's close aides, Minister Ron Dermer, had invited him to his residence.

In discussions with Israeli officials, he also didn't hesitate to point out all that Trump had done for Israel.

In his first term, Trump moved the US Embassy from Tel Aviv to occupied Jerusalem, recognized the occupied Syrian Golan Heights as Israeli territory and cut US aid for the Palestinians.
