US Vice President JD Vance said Sunday that Washington and Tehran have not yet reached an agreement as high-stakes US and Iran talks stretched into a second day, Anadolu Ajansi reported.

"The bad news is that we have not reached an agreement, and I think that's bad news for Iran, much more than it's bad news for the United States," Vance told US journalists at a hotel where the American and Iranian delegations have been holding talks since Saturday.
