Trump says Iran has 15 days to reach a deal or face 'unfortunate' outcome

Iran has a short window to agree to a deal with the U.S., President Donald Trump said Thursday, before warning that the situation could soon shift if negotiations fail.

The talks focus largely on curbing Tehran’s advancing nuclear program, which U.S. officials say has moved closer to weapons-grade enrichment.

The U.S. and Israel also want Iran to give up its long-range ballistic missiles, stop supporting groups around the Middle East and stop using force against protesters inside Iran.
