U.S. President Donald Trump said negotiations with Iran would resume Monday, after scrapping a planned military strike over the weekend. Speaking on Sunday, the American leader also refused to set a deadline for reaching a broader deal with Tehran.

“They knew the extent of the attack because they saw it forming. Now what we’re doing is we’re talking to them in the form of a negotiation. It begins tomorrow afternoon, and we’ll see,” said Trump, talking to reporters aboard Air Force One.

Asked whether he had imposed a deadline, the U.S. president responded: “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’s remarks came on the heels of his early Sunday announcement on Truth Social that the U.S. was shelving a “massive attack,” after Iran and several Middle Eastern countries asked Washington to pause military action while negotiators worked toward an agreement. He said the framework under discussion included the “Immediate, Complete, and Total OPENING OF THE HORMUZ STRAIT” and an end to Iran’s nuclear threat, adding that Israel had also agreed to pause strikes.

So far, Tehran has not yet publicly confirmed it will take part in negotiations.
