US President Donald Trump signaled a possible second round of Iran talks that could happen in Pakistan or Geneva, Switzerland, within the next two days.
The first round of talks in Islamabad ended over the weekend without a deal, but officials indicated a likely date for the next round.
US officials told AFP that discussions were still underway about a new round of talks, and a diplomat from a mediating country said that Tehran and Washington had agreed to it.
However, the venue, schedule, and composition of delegations are yet to be finalized, with Islamabad and Geneva under consideration as possible hosts.
The first round of talks held in Islamabad over the weekend ended without yielding results, with one of the sticking points being the Strait of Hormuz.
US Treasury Secretary Scott Bessent hinted that the negotiations have started, stating that the US has begun negotiations with Iran and has identified interlocutors capable of representing all three branches of Iran's government.
