A U.S. official said that President Donald Trump is ‌unhappy with an Iranian proposal because it did not address Iran’s nuclear program, according to Reuters.

“He doesn’t love the proposal,” Reuters quoted the U.S. official as saying, 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, Reuters reported citing sources from mediator Pakistan.
