"We have reached a conclusion on a large portion of the issues under discussion," said an Iranian spokesperson. "But to say that this means the signing of an agreement is imminent—no one can make such a claim.”

Optimism for a US-Iran peace deal appeared to be mounting again, although such hopes have risen in the past only to be dashed amid threats of mass destruction from both sides.

US President Donald Trump stated that a peace deal with Iran is largely negotiated, signaling potential progress toward reopening the Strait of Hormuz after months of conflict.
