ABOARD AIR FORCE ONE/CAIRO, Aug 3 (Reuters) - U.S. President Donald Trump said talks ​with Iran will happen on Monday but declined to set a deadline for an agreement after earlier saying he had called off an ‌imminent attack in hopes of quickly reaching a deal to reopen the Strait of Hormuz and resolve the impasse over Tehran's nuclear capabilities.

Trump had said late on Saturday on his Truth Social platform that Iran and other Middle Eastern countries had asked for time to complete a deal that would lead to "the Immediate, Complete and Total" reopening of the strait and "an end to ​Iran's nuclear threat" but that Tehran must "rapidly make a DEAL."

As he returned to Washington from a weekend in New Jersey, Trump told reporters on Sunday ​that a negotiation would begin on Monday afternoon but did not provide details of where it would take place or ⁠who would be involved.

Asked if there was a deadline for Iran to come to an agreement, Trump declined to answer. "Would I rather make a deal? I'm not ​looking to kill people because people die, a lot of people die, and we don't want that," Trump said in response.

Trump has repeatedly issued threats that he would ​escalate the war on Iran he launched along with Israel in late February, only to allow more time for talks, which have so far not led to a comprehensive deal.

Trump's apparent de-escalation after days of threats of new attacks from each side was the latest twist in the war. Attacks have spread across the Gulf to the Red Sea and even a Mediterranean facility ​in Egypt.

Iran has largely closed the Strait of Hormuz, a conduit for 20% of the world's oil and liquefied natural gas before the start of the war, ​causing energy prices to rise and stoking broader inflation.

The U.S. president has argued that his stated goal of keeping Iran from gaining nuclear weapons justifies higher fuel costs in the near ‌term, but ⁠the economic pain has put political pressure on him to find a way to end the conflict.

Oil prices were down more than 4% in early trading on Monday.

Iran's Foreign Minister Abbas Araqchi held phone calls with his Saudi counterpart Prince Faisal bin Farhan and Pakistan's army chief Asim Munir to discuss diplomatic efforts, Iran's state media reported on Sunday.

The official Iranian news agency IRNA reported earlier that negotiations between Tehran and Oman over the Strait of Hormuz were in their final stages, ​citing Iran's Foreign Minister Abbas Araqchi.

Iranian Foreign ​Ministry spokesperson Esmaeil Baghaei said negotiations ⁠were focused on agreeing a new route through the strait, adding that it had "no link to the Strait of Hormuz being opened or closed. That is a separate discussion."

Last month Iran publicly rejected an Omani proposal, backed by Gulf states, to manage ​the strait they share. People familiar with the matter had told Reuters the plan included the collection of voluntary fees ​for using the strait.

Eli ⁠Cohen, Israel's energy minister and a member of Prime Minister Benjamin Netanyahu's security cabinet, said there was close security and intelligence coordination between Israel and the U.S. on everything happening in the region.

But he added: "With or without an agreement, and regardless of any external commitments, if Iran attempts to renew its nuclear program or advance its ballistic missile ⁠industries, we ​will be there. We will take action, and we will strike."

Trump and Netanyahu met on Tuesday ​in Washington, with an Israeli official saying they had explored all possible paths to curb Iran's nuclear program, including diplomacy, economic pressure and force. Tehran denies it is seeking a nuclear weapon.
