President Donald Trump is nearing a deal with Iran to end the war, he announced on Saturday, though details of the agreement remain unclear.

After holding a call with officials from the United Arab Emirates, Saudi Arabia, Qatar, Turkey, Pakistan, Jordan, Bahrain and Egypt, as well as a separate discussion with Israeli Prime Minister Benjamin Netanyahu, Trump said on Truth Social on Saturday afternoon that an agreement has “been largely negotiated” with “final aspects and details … currently being discussed.” 

“In addition to many other elements of the Agreement, the Strait of Hormuz will be opened,” the president said.

While Trump did not offer any further details, Iranian officials had told The New York Times that a memorandum of understanding under discussion with the U.S. would end fighting on all fronts, including between Israel and Lebanon; lift the U.S. blockade of Iranian ports and allow for free movement of commercial traffic without any tolls; leave nuclear issues to be negotiated within 30 to 60 days; and see the release of $25 billion in frozen Iranian funds. 

U.S. officials told the Times that, under the current agreement, Tehran has committed to giving up its stockpile of already enriched uranium, an issue that Trump has frequently stated is a U.S. priority, but the specifics as to how that transfer will occur are set to be worked out in subsequent negotiations.

It remains unclear if other issues, including Iran’s ballistic missile program and support for proxies, will be addressed in the deal. 

Some hawkish Senate Republicans expressed outrage on Saturday over the reported terms of the deal, calling it a defeat for the United States filled with major concessions to the Iranian regime.
