US President Donald Trump said Monday that he has put on hold a planned military strike on Iran after requests from leaders of Qatar, Saudi Arabia and the United Arab Emirates, who believe negotiations are nearing a breakthrough.

In a post on Truth Social, Trump said he had instructed US military leaders to remain ready for a “full, large scale assault” on short notice if talks fail.

“We were getting ready to do a very major attack tomorrow. I put it off for a little while — hopefully maybe forever,” Trump told reporters at the White House, adding that Gulf states requested a short delay because they see a strong chance for a deal.

Trump said any agreement must ensure that Iran does not obtain nuclear weapons.

The US president also said recent discussions with Iran appeared more promising than previous rounds of negotiations, though he cautioned that it remains unclear whether a final agreement can be reached.

According to sources familiar with the matter, Trump had been presented with military strike options after growing frustrated with slow-moving negotiations. However, Iran’s latest proposal reportedly failed to offer major concessions on key disputes, particularly over uranium enrichment and Tehran’s near-weapons-grade uranium stockpile.

Iran earlier said it had responded to US concerns through Pakistani mediators, but American officials reportedly did not consider the changes significant enough.

The war, now in its third month, has also added pressure on Trump domestically, with rising fuel prices and declining approval ratings on the economy.
