Egyptian President Abdel Fattah El-Sisi has invited President Donald Trump to attend the signing of a potential Gaza peace agreement once it is reached, a move that may signal progress in ongoing negotiations.

Sisi made his remarks during a televised address at a police academy in Cairo, adding that special envoy Steve Witkoff and Jared Kushner arrived late Tuesday evening.

Ron Dermer, Israel’s lead negotiator and one of Prime Minister Benjamin Netanyahu’s closest advisers, has arrived in Sharm el-Sheikh, Egypt, for indirect ceasefire talks, two sources familiar with the matter told ABC News.

Steve Witkoff, the U.S. special envoy to the Middle East, and Jared Kushner were scheduled land in Egypt on Wednesday to join talks aimed at finalizing a ceasefire deal between Israel and Hamas, according to an official familiar with their travel plans.

The pair were expected to depart for the Middle East on Tuesday, the official said.

Another official said that Witkoff and Kushner have been closely following the progress of the talks from afar and frequently communicating with mediators. Those indirect talks began on Monday.

President Donald Trump on Tuesday said, "We are very close to making a deal on the Middle East that will bring peace."

Al Thani’s participation "comes at a critical stage of the talks, reaffirming the determination of the mediators to reach an agreement that would bring an end to the catastrophic war in the Gaza Strip," the spokesperson said in the post.
