The Trump administration has named US Secretary of State Marco Rubio and former UK prime minister Sir Tony Blair as two of the founding members of its 'Board of Peace' for Gaza.
Trump's Middle East envoy Steve Witkoff and the president's son-in-law Jared Kushner will also sit on the 'founding executive board,' the White House said in a statement on Friday.
Trump will act as chairman of the board, which forms part of his 20-point plan to end the war between Israel and Hamas.
It is expected to temporarily oversee the running of Gaza and manage its reconstruction.
Also on the founding executive board are Marc Rowan, the head of a private equity firm, World Bank chief Ajay Banga, and US national security adviser Robert Gabriel.
Each member would have a portfolio 'critical to Gaza's stabilisation and long-term success,' the White House statement said.
Trump said on Thursday that the board had been formed, calling it the 'Greatest and Most Prestigious Board ever assembled at any time, any place.'
Further members of the board would be named in the coming weeks, the White House said.
Sir Tony was UK prime minister from 1997 to 2007 and took the UK into the Iraq War in 2003. After leaving office, he served as Middle East envoy for the Quartet of international powers (the US, EU, Russia, and the UN).
It comes after the announcement of a separate 15-member Palestinian technocratic committee, the National Committee for the Administration of Gaza (NCAG), charged with managing the day-to-day governance of post-war Gaza.
Ali Shaath, a former deputy minister in the Palestinian Authority (PA) which governs parts of the occupied West Bank not under Israeli control, will head that new committee.
The statement also said that Nickolay Mladenov, a Bulgarian politician and former UN Middle East envoy, would be the board's representative on the ground in Gaza working with the NCAG.
Trump's plan states an International Stabilisation Force (ISF) will also be deployed to Gaza to train and support vetted Palestinian police forces, with US Major General Jasper Jeffers heading this force to 'establish security, preserve peace, and create a durable terror-free environment.'
The White House noted the formation of a separate 'Gaza executive board' to aid governance, which includes some of the same individuals as the founding board along with additional appointees.
Under phase one, Hamas and Israel agreed to a ceasefire in October, as well as a hostage-prisoner exchange, a partial Israeli withdrawal, and an aid surge.
Witkoff mentioned that phase two entails Gaza's reconstruction and disarmament of Hamas and other groups, making compliance paramount.
Meanwhile, humanitarian conditions deteriorate, with reports indicating serious military and civil losses on both sides following the October conflict start.
