A U.S. official said on ​Monday that President Donald Trump is ‌unhappy with an Iranian proposal because it did not address Iran's nuclear program.

"He doesn't love ​the proposal," the U.S. official said, ​referring to Trump.

Earlier in the day, Trump discussed ⁠the proposal with his top national ​security aides. The U.S.-Iran conflict remains in ​a stalemate with energy supplies from the region reduced.

Iranian sources earlier on Monday said the proposal would ​set aside discussion of Iran's nuclear ​program until the war has ended and disputes ‌over ⁠shipping from the Gulf are resolved. Washington has said nuclear issues must be dealt with from the outset.

Work to bridge gaps ​between the ​U.S. ⁠and Iran has not halted, sources from mediator Pakistan have said.

But ​hopes of reviving peace efforts ​have ⁠receded since Trump announced this weekend he had scrapped a visit by his special ⁠envoy ​Steve Witkoff and son-in-law Jared ​Kushner to Islamabad, the Pakistani capital.
