TEHRAN — Iranian Foreign Minister Abbas Araghchi described Friday's negotiations with the United States in Muscat as "a good start," signaling cautious optimism while underscoring uncertainty over what comes next.

In remarks to state television after the talks, Araghchi said the two sides held "intensive and lengthy" indirect discussions and exchanged their "views and concerns." He added that "the continuation of the negotiations is subject to consultations in the capitals," suggesting the diplomatic track remains open, albeit fragile.

The minister noted that the negotiations with the United States focused solely on the nuclear issue. "We are not discussing any other issue with the Americans," he said. Iran has made it clear, he added, "that the prerequisite for any dialogue is refraining from threats and pressure."

Before the talks, US Secretary of State Marco Rubio declared that Washington is seeking a deal that addresses Tehran's nuclear program, the range of its missiles, its support for regional proxy groups and its treatment of Iranian people.
