DUBAI, United Arab Emirates (AP) — President Donald Trump said Monday that Iran had requested a meeting with U.S. counterparts, though one of Iran's top negotiators said no further talks had been scheduled after attacks across the Persian Gulf over the weekend challenged negotiations to end the war.

The U.S. president has tried to preserve a fragile interim deal, but hostilities mounted in recent days in the Strait of Hormuz, through which a fifth of the world's oil had been shipped before war began. After four days of trading strikes, both sides appeared to pause their attacks Monday.

Trump said on social media that a meeting with Iran would happen Tuesday in Doha, Qatar. Trump special envoy Steve Witkoff and Jared Kushner, the president's son-in-law, are flying to Qatar for the meeting, White House press secretary Karoline Leavitt told Fox News' "Fox & Friends."

But Kazem Gharibabadi, a senior negotiator for Iran, denied any talks had been scheduled.
