As might have been expected, President Donald Trump’s Gaza peace plan has been put on hold amid the war with Iran, an exclusive report by Reuters revealed Monday.

The peace plan represented a major policy goal of the Trump administration, and the freeze may present a setback to the plan. Countries in the Middle East who had pledged billions just a few weeks ago to rebuild Gaza are now reeling from attacks Iran has launched at them after the United States and Israel embarked on a joint military operation against Iran last week, triggering a wider regional conflict.

Trump has made it clear that the peace plan can only proceed if Hamas disarms, and talks about disarmament had been ongoing until the war with Iran broke out. Sources with knowledge of the talks, who remained anonymous due to the sensitivity of the negotiations and because the disruption had not been previously reported, said that talks have now been paused.

Nevertheless, a White House official denied that the peace plan and discussions about Hamas’ disarmament have been frozen.

“Discussions on disarmament are ongoing and positive,” he said. “All of the mediators agree that this is a critical step to enable rebuilding for the people of Gaza.”

One source familiar with the peace plan dismissed concerns that the delay would negatively impact the plan. He said that travel disruptions had affected the ability to conduct talks — which had taken place in Cairo, Egypt — but would resume once travel was restored. He also said that the severe degradation of Iran’s military capabilities would have a positive impact, since Iran had provided much of Hamas’ weaponry.

An unnamed Palestinian official confirmed that talks had been frozen, and Israel’s government declined to comment. However, a U.S. official whose name has been withheld said, “The situation in the region has impacted some travel, but discussions and progress continue.”

Israel has slowed down its strikes on Gaza, saying it still needs to respond to threats. But Gaza residents expect the strikes to step up again after the war with Iran ends, according to reports.

Trump’s peace plan, beginning with the October ceasefire between Israel and Hamas, quickly expanded into an initiative joined by multiple countries in Europe and the Middle East. The U.S. has been running the internationally coordinated effort out of headquarters in southern Israel, but movement toward implementation has slowed since the war started. Several diplomats said the Civil Military Coordination Center is operating at minimal levels, partly to protect against Iranian attacks.

While high-level discussions on Gaza have ceased, countries have engaged in low-level discussions to keep the plan in place and ensure forward momentum when the war is over.
