Iran is preparing a counter-proposal after rejecting the U.S. nuclear deal, prompting President Trump to caution that "time is running out."

US President Donald Trump asserts that Iran won’t be allowed to enrich uranium, despite reports that the deal Washington has proposed would allow Tehran to do so at low levels for a temporary period.

WASHINGTON (AP) — President Donald Trump on Monday appeared to undercut a proposal that was offered by his special envoy to Iran, saying he will insist that Tehran fully dismantle its nuclear enrichment program as part of any deal to ease crushing sanctions.
