US special envoy Steve Witkoff announced the launch of Phase II of US President Donald Trump's Gaza Peace Plan on Wednesday.

Sources familiar with the details told The Jerusalem Post in advance that Trump would announce a move to Phase II on Wednesday.

"We are announcing the launch of Phase II of the President’s 20-Point Plan to End the Gaza Conflict, moving from ceasefire to demilitarization, technocratic governance, and reconstruction," Witkoff wrote on X/Twitter.

"Phase II establishes a transitional technocratic Palestinian administration in Gaza, the National Committee for the Administration of Gaza (NCAG), and begins the full demilitarization and reconstruction of Gaza, primarily the disarmament of all unauthorized personnel," he added.

"The US expects Hamas to comply fully with its obligations, including the immediate return of the final deceased hostage. Failure to do so will bring serious consequences," he said.

"Phase I delivered historic humanitarian aid, maintained the ceasefire, returned all living hostages, and the remains of twenty-seven of the twenty-eight deceased hostages. We are deeply grateful to Egypt, Turkey, and Qatar for their indispensable mediation efforts that made all progress to date possible," Witkoff commented.

Trump is due to give a press statement and answer questions at 9 p.m. Israel time (2 p.m. Washington time).

Gvili's mother: Netanyahu affirmed Ran's return is 'our top priority'

Talik Gvili, mother of slain hostage St.-Sgt.-Maj. Ran Gvili, confirmed that Prime Minister Benjamin Netanyahu called her and confirmed that the return of her son's remains from Gaza is "our top priority."

Gvili is the final hostage whose remains are still being held in the Gaza Strip by Hamas and other terror groups.

The move establishing a technocratic committee to govern the strip, and "any other action," would not affect efforts to return Gvili's remains, Talik said.

"The statement on Phase II focuses on the demand of disarming Hamas terrorists and demilitarizing the Gaza Strip. There will be no IDF withdrawal until they are disarmed, no construction, and no reconstruction," she said.

The Rafah Border Crossing has not yet been reopened because "we insist on [bringing Ran's remains home]," she noted.

Efforts to return his remains are "being carried out in the intelligence and operational echelons, as well as via talks with mediators," she elaborated.

"We have clear demands from Hamas because we passed on intelligence information, and things we have requested have not yet happened. Therefore, anything that is expected to happen will not affect the efforts and the demand to return Ran," she affirmed.

Hostages and Missing Families Forum denounces Phase II, while Gvili's remains still held in Gaza

The Hostages and Missing Families Forum, earlier on Wednesday, denounced the expectation that the Trump administration will proceed into Phase II, due to Gvili's remains still being held in Gaza.

"This morning, the Hostages and Missing Families Forum, together with the Gvili family, is calling on Prime Minister [Benjamin] Netanyahu to honor his commitment, as he promised the family in private conversations, not to proceed to Phase II until Ran is brought home," the forum wrote on their official social media.

"Moving to Phase II now, while efforts to secure Ran's return have not been exhausted, would mean giving up the most significant source of leverage and could effectively condemn Ran to permanent disappearance," the forum said.

"Until Ran is returned, the State of Israel will not be able to close its deepest open wound or begin the process of recovery and healing that it so desperately needs. Phase II cannot be implemented while Ran remains in captivity," the forum insisted.

Palestinian Authority Vice President Hussein al-Sheikh praises launch of Phase II

"The Palestinian Presidency welcomes" Trump's efforts, including "the establishment of the Board of Peace and its executive bodies," Palestinian Authority Vice President Hussein al-Sheikh wrote on X/Twitter.

"The Presidency announces its support for the formation of the Palestinian Committee for the Administration of Gaza during this transitional phase," he added.

"The Presidency has maintained close coordination with the Special Envoy for Peace Mr Steve Witkoff, Mr Jared Kushner and the US teams and Mr Nickolay Mladenov in support of the United States’ efforts to consolidate the ceasefire and to move to the second phase of its implementation, including reconstruction," Sheikh said.

"The Palestinian Presidency reiterates the importance of linking the institutions of the Palestinian Authority in the West Bank and the Gaza Strip, and not creating any administrative, legal, or security arrangements that would entrench duplication, division, separation, or fragmentation, with upholding the principle of one system, one law, and one legitimate weapon," he commented.

"The Presidency further stresses the importance of working with the United States and relevant partners to take decisive steps in the West Bank in parallel with the transitional phase in Gaza. This includes ensuring a halt to unilateral actions that violate international law, preventing settlement expansion plans and settler terrorism, releasing withheld Palestinian funds, preventing displacement and annexation, and preclude any undermining of the Palestinian National Authority and the two-State solution," he continued.

"The Presidency call upon all Palestinian factions, national institutions, civil society organizations, and all segments of Palestinian society to assume their national and historical responsibilities, and to act in a spirit of partnership and highest sense of responsibility in order to ensure the success of this critical transitional phase," he concluded.

Zini, Ben-Gvir disagree over proposed names of Gaza technocratic gov't. - N12

An argument erupted between National Security Minister Itamar Ben-Gvir and Shin Bet (Israel Security Agency) chief David Zini at a cabinet meeting on Tuesday, N12 News reported.

During the meeting, Zini stated that Shin Bet approved the names of 15 members of the proposed technocratic government to oversee the Gaza Strip per Phase II of Trump's plan. Zini affirmed that none of the members were affiliated with either Hamas or the Palestinian Authority, N12 noted.

Ben-Gvir disagreed, noting that one was a deputy minister under then-PA president Yasser Arafat, according to the report.

Zini argued that he met all the criteria set, but Ben-Gvir refuted this.

N12 approached both Zini and Ben-Gvir's offices, and neither denied the details in the report.

Egypt, Turkey, Qatar praise formation of technocratic government

Egyptian Foreign Minister Badr Abdelatty affirmed that an agreement over the members forming the technocratic government had been reached during a press conference on Wednesday.

The Egyptian Foreign Ministry released a joint statement with Qatar and Turkish partners praising the formation of the technocratic government.

This is a "significant development that will contribute to strengthening efforts aimed at consolidating stability and improving the humanitarian situation in the Gaza Strip," the statement read.

We "hope that the formation of the committee will pave the way for the implementation of the second phase of the ceasefire agreement in the Gaza Strip," the statement continued.

This "will contribute to consolidating the truce and preventing renewed escalation," it affirmed.

The three countries, referring to themselves as "the mediators," stressed "the necessity for all parties to fully implement the agreement in order to achieve a sustainable peace and create the appropriate conditions for the reconstruction of the Gaza Strip, thus fulfilling the aspirations of the brotherly Palestinian people for security, stability, and a dignified life."

The statement also confirmed that Ali Shaath would lead the technocratic government. This is the former PA minister whose history reportedly caused the aforementioned argument between Zini and Ben-Gvir.

The committee is expected to hold its first meeting at the US Embassy in Cairo on Thursday, and is due to hold future meetings at a temporary headquarters in Egypt, while five offices will be established in the Gaza Strip to coordinate with the committee, Israeli public broadcaster KAN News reported on Wednesday.

This is a developing story.
