Iran live updates: 8 Marines hurt in ship attack in Strait of Hormuz

After President Donald Trump rejected a proposal from Iran over the weekend, U.S. officials said he remains open to offering the country sanctions relief and releasing its frozen assets in exchange for concrete progress toward a nuclear deal.

Trump confirmed U.S. and Iranian officials spoke via mediators on Monday.

The Trump administration has always said Iran would receive substantial financial rewards if it walked away from its nuclear program, and under June’s memorandum of understanding, the U.S. promised to roll back all sanctions as part of a verifiable, long-term nonproliferation deal. Iran has not indicated it’s willing to bring the nuclear issue into negotiations at this point.
