Neither the United States nor Iran has launched attacks over the past three nights, following nearly two weeks of reciprocal strikes that threatened to derail talks aimed at bringing the war to a definitive end.

President Donald Trump suspended US attacks against Iran for a third consecutive night to give diplomacy more time, according to the US ambassador to the United Nations. Speaking on Fox News on Sunday, Ambassador Mike Waltz said the president was "giving the talks some space and allowing them a degree of flexibility."

An Iranian military spokesperson said Sunday that Tehran had responded by suspending its "retaliatory" attacks in the region. The pause follows nearly two weeks of daily US strikes and reciprocal action that effectively undermined the ceasefire reached in June.

Oil prices fell sharply after the pause, dropping below $90 a barrel on Monday morning after reaching $100 for the first time since May.

Asked whether Trump had decided against further escalation for now, Waltz told NBC: "I would not go so far as to say that at all." Speaking to CBS, he added: "We will see in the coming days. But let me be clear: additional military assets are heading to the region."

"The regime should believe the president when he says they are prepared to act and that all options are on the table."

As of Monday, Trump had not commented publicly on the latest developments. He had previously posted computer-generated images on his Truth Social account depicting US military aircraft bombing Iranian ships and Kharg Island.

The pause follows 13 consecutive nights of US attacks on Iran, which Washington said were intended to "reduce Iran's ability to threaten commercial shipping in the Strait of Hormuz."

Meanwhile, Iran and Oman held several rounds of technical talks in Tehran on Friday and Saturday to discuss management of the Strait of Hormuz, according to Iranian Foreign Ministry spokesperson Esmail Baghaei.

Disputes over control of the strait reignited tensions between the United States and Iran earlier this month and remain one of the main obstacles to a lasting end to the war. In June, Iran and the United States signed a memorandum of understanding to halt military operations.
