US Vice President JD Vance on Thursday announced the official start of the next phase of negotiations with Iran following the conclusion of a framework agreement aimed at ending hostilities between the two countries.
The 60-day period set out in the memorandum of understanding had "officially started today," Vance told reporters at the White House.
During that time, negotiators are expected to tackle some of the most contentious and unresolved issues that were left open in the initial accord. These include key questions surrounding Iran's nuclear programme and the future of its stockpiles of highly enriched uranium.
The 60-day deadline can be extended if both sides agree.
According to Pakistan, which mediated the agreement, the framework accord entered into force with "immediate effect" overnight into Thursday after it was signed by both parties.
Vance said the agreement had already been signed electronically.
"We're going to start the 60-day clock today," he said.
