After 13 nights of intensifying US air strikes on Iran, the Pentagon abruptly suspended the campaign late on Friday, with no US attacks reported on either Saturday or Sunday.
Iran, which had been following each night of US attacks with its own strikes on neighboring countries that host US bases, has also so far held fire for two days.
The US ambassador to the United Nations, Mike Waltz, told Fox News on Sunday that Trump had decided to pause US attacks to allow more time for diplomacy.
"He's giving talks some space, he's giving it a little bit of room," Waltz said, without providing further details.
The senior Iranian source, speaking on condition of anonymity, told Reuters: "Iran’s position remains ‘attack for attack’: if the attacks stop, Iran will also halt its operations. That message has already been conveyed to the United States."
