Trump escalates pressure on Iran as 60-day deadline for nuclear deal expires without agreement

The 60-day window for the US and Iran to reach a final agreement on their nuclear deal has expired without an announcement, as President Trump increases pressure on Tehran with tougher demands. Trump's administration is now moving towards a 'new pressure campaign' that could lead to further escalation. The White House has called for Iran to show its commitment to the deal by waving a 'white flag'.
