The United States, Germany, France and Britain warned Iran on Saturday to resume compliance with a 2015 nuclear deal in order to "avoid a dangerous escalation".
Leaders of the four countries repeated that they wanted dialogue. But that "This will only be possible if Iran changes course," US President Joe Biden, German Chancellor Angela Merkel, French President Emmanuel Macron and British Prime Minister Boris Johnson said in a joint statement.
"We call upon President (Ebrahim) Raisi to seize this opportunity and return to a good faith effort to conclude our negotiations as a matter of urgency. That is the only sure way to avoid a dangerous escalation, which is not in any country's interest," they said after meeting on the sidelines of a summit of the Group of 20 richest nations.
The four leaders met to discuss Iran while in Rome to attend the G20 summit.
Iran has recently speeded its ongoing breaches of the deal’s restrictions on its nuclear activities, apparently to pressure US President Joe Biden to lift sanctions against Tehran.
