“It is worrying that Iran is choosing to continue to escalate its nonperformance of its JCPOA commitments, especially with experiments that have value for nuclear weapons research,” State Department spokesman Ned Price told reporters, referring to the joint comprehensive plan of action reached between Iran and six nations on restricting Tehran’s atomic program.
“We continue to urge Iran to stop this brinksmanship, to return to Vienna prepared for real talks, and to be in a position to be prepared to finish the work that we have started in April,” he said.
