US President Donald Trump plans to hold a summit of world leaders on Gaza during his visit to Egypt, four sources familiar with the matter told Axios.

The summit could help garner more international backing for Trump's Gaza peace plan, though challenging agreements regarding post-war governance, security, and reconstruction remain unresolved.

The summit is being organized by Egyptian President Abdel Fattah el-Sisi, who has already extended invitations to several European and Arab leaders, according to the sources.

According to the sources, leaders or foreign ministers from Germany, France, the UK, Italy, Qatar, the UAE, Jordan, Turkey, Saudi Arabia, Pakistan, and Indonesia are expected to participate, while a US official said Israeli Prime Minister Benjamin Netanyahu is not currently anticipated to attend.

US officials have confirmed Trump's plans to attend the summit, but the White House has declined to comment.

Trump to join signing ceremony

On Monday afternoon, Trump will travel to Egypt to meet with President el-Sisi and participate in a signing ceremony with the other guarantors of the Gaza peace deal: Egypt, Qatar, and Turkey. The main leaders' summit is likely to be held on Tuesday morning in Sharm el-Sheikh, but could be moved to Monday, according to the sources.

Trump previously hinted at this visit to Egypt on October 9, telling reporters that talks with Hamas were going well and that he might travel to the Middle East the following Sunday, while also noting that all Islamic and Arab countries were involved in the process, which he called an unprecedented development.

In a statement on October 8, US Secretary of State Marco Rubio said Trump would be interested in visiting the Middle East to attend the signing ceremony for a Gaza peace agreement, if a deal is reached.

"Potentially, the president [Trump] will have to make that decision, but I anticipate that he would be interested in doing so if the timing could work out," Rubio told The Washington Examiner.
