Witkoff points to "significant announcements" coming regarding more countries joining the Abraham Accords.

US Special Envoy for the Middle East Steve Witkoff told CNBC on Wednesday that more countries are expected to join the Abraham Accords normalization agreement with Israel. Witkoff also noted ongoing discussions with Iran regarding its nuclear program.

"We believe we have significant announcements regarding countries joining the Abraham Accords," Witkoff said, without specifying which countries might be participating.

Regarding Iran, Witkoff expressed hope for a comprehensive peace agreement, noting a "strong sense of Iran's readiness" to move toward peace. He added that current talks with Iranian officials are focused on establishing a civilian nuclear program. However, he emphasized a key condition: "It cannot be enriched."

"Iran's attempt to enrich uranium again is a red line," Witkoff added.

US President Donald Trump confirmed on Wednesday that American and Iranian officials would hold talks next week, raising cautious hopes for a long-term peace deal a day after a fragile ceasefire held despite Tehran's insistence that it will not abandon its nuclear program.

Trump, who negotiated the ceasefire that took effect Tuesday on the 12th day of Israel's war on Iran, confirmed at the NATO summit in The Hague that he was not particularly interested in resuming negotiations with Iran, insisting that US strikes had destroyed its nuclear program.

"We might make a deal, I don't know. As far as I'm concerned, I don't think it's that necessary," Trump said. "From my perspective, they fought, and the war is over."

A number of US media outlets questioned the results of the strikes on Iranian nuclear facilities.

These outlets published a leaked preliminary intelligence assessment stating that the US airstrikes did not destroy Iran's nuclear capability but merely delayed its development by a few months.

"The intelligence...is not entirely conclusive," the US president told reporters during a meeting with NATO Secretary General Mark Rutte.

He added: "Intelligence says we don't know. It may have been very serious. That's what the intelligence indicates, but I think we can accept the phrase 'we don't know.' The damage was very serious. It was complete destruction."

Iran insists it will not abandon its nuclear program, and its parliament has approved a motion that would effectively halt the country's cooperation with the International Atomic Energy Agency.

Iran has also not confirmed any talks next week, and an Iranian official questioned whether the United States could be trusted after its weekend attack on Iranian nuclear sites.
