Iranian President Hassan Rouhani warned the world powers of Tehran's serious reaction to their lagging and delay in implementing their undertakings under the Vienna nuclear agreement, Fars reports.
"We should monitor and verify the other side's performance," Rouhani said, addressing a cabinet meeting in Tehran on Wednesday.
"If we see any lagging and shortages from the other side, we should certainly show serious reaction," he added.
His remarks came after Iranian Foreign Minister Mohammad Javad Zarif and his US counterpart John Kerry in a meeting in New York conferred on Washington's undertakings under the nuclear deal whose implementation has been delayed.
