U.S. President Donald Trump said he would "hold off" an attack on Iran scheduled for Tuesday at the request of Gulf leaders.

Trump said on his Truth Social network on Monday that "serious negotiations" were now underway with Iran and that Gulf states believed "a deal will be made."

U.S. President Trump on Monday said that he is “not open” to any concessions for Tehran after receiving the latest Iranian response on peace deal talks.

Iran has given an updated proposal for a deal to end the war, but the White House believes it is not a meaningful improvement and is insufficient for a deal, a senior U.S. official and a source briefed on the issue told U.S. news portal Axios.

Iran's top security body announced on Monday the formation of a new body to manage the Strait of Hormuz, which Tehran has effectively closed and wants to charge ships to traverse.

Iran's Revolutionary Guards said Monday their forces had struck groups linked to the United States and Israel in the western Iranian province of Kurdistan, near the border with Iraq.

A drone strike sparked a fire on the edge of the United Arab Emirates’ sole nuclear power plant on Sunday in what authorities called an “unprovoked terrorist attack.” No one was blamed, but it highlighted the risk of renewed war as the United States and Iran signaled they were ready to fight again.

Iran said Monday it had responded to a new U.S. proposal aimed at ending the war, adding that diplomatic exchanges continue despite Iranian media reports describing Washington's demands as excessive.

The Israeli military intercepted Monday boats off the coast of Cyprus, part of the latest wave of flotilla activists attempting to break Israel's naval blockade of Gaza.

More than 50 vessels departed from the port in Marmaris, Turkey, last week in what the organizers of the Global Sumud Flotilla described as the final leg of their planned journey to Gaza's shores.

U.S. President Donald Trump has threatened Iran over its blockade of the Strait of Hormuz, posting an AI-generated picture on his Truth Social platform with Iranian-flagged naval vessels warning, "It Was The Calm Before the Storm."

Trump also warned in comments that Iran should make a deal with the U.S., saying, "if they don't, they're going to have a bad time. A very bad time."

Iranian state television said on Saturday that European countries were in talks with Tehran over transit for ships through the Strait of Hormuz.
