US President Donald Trump has warned Iran on Tuesday, to honor its commitments to the 2015 nuclear deal and threatened "big problems" if it didn't.
A week after certifying Iran as complying with the agreement negotiated by President Barack Obama, Trump made it clear to a crowd of thousands of raucous supporters in Youngstown, Ohio that he remains extremely wary of Tehran.
Meanwhile on Tuesday, a US navy ship fired warning shots towards an Iranian vessel in the Persian Gulf, for sailing too close.
The shots were fired after the Iranian vessel came within 130 meters of the navy ship, and failed to respond to radio calls, flares and the ship's whistle.
