Trump claims Tehran wants a deal 'quickly'

He made his comments came after Gulf Arab states postponed a planned meeting with Iran and Yemen's Iran-aligned Houthis launched a fresh attack on Saudi Arabia, highlighting fears the conflict could spread further across the region.

The Houthis said they fired dozens of missiles and drones at a military airbase in Khamis Mushait in southern Saudi Arabia, targeting aircraft hangars, radar systems, runways and ammunition depots in retaliation for Saudi airstrikes in Yemen. Saudi authorities issued emergency alerts there and in three other southern cities which have previously come under Houthi fire.

Crude oil prices rose more than 4% on Monday when the market reopened after the weekend's developments, before paring some gains during US morning trade.

Oman had been due to host a meeting on Monday with Iran and Gulf states to discuss negotiations aimed at reopening Hormuz, the world's most important oil shipping lane, largely closed since the US and Israel attacked Iran at the end of February. But Oman's Foreign Minister Sayyid Badr Albusaidi announced overnight that the meeting had been postponed.

Iran said the postponement was at the request of Saudi Arabia. Iran meanwhile published a list of 77 ships it said had violated its operating protocols in Hormuz and warned they could face fines, detention or confiscation on future transits.

Saudi state media reported that Crown Prince Mohammed bin Salman met US regional commander Admiral Brad Cooper in Jeddah on Monday. Three sources have so far resisted Saudi requests for direct military intervention beyond intelligence support.

Trump said over the weekend he had spoken with the crown prince and that the Houthis had also contacted Washington urging it to stay out of the conflict. The United States bombed Houthi targets for two months in 2025 before Trump halted the campaign after reaching a ceasefire with the group.
