Washington: US President Donald Trump issued a fresh warning to Iran by sharing a photo that appears to show him holding a gun, saying he would not be “nice anymore.”

Though a ceasefire with Iran is said to be in effect, Trump has continued to deliver sharp messages, alleging that Tehran has failed to finalize a nuclear agreement.

In his post, Trump claimed Iran has not “woken up” and does not know how to sign a deal that keeps it without nuclear weapons.

He added that Iran must act wisely and do so quickly, reiterating his demand for an agreement that prevents nuclear armament.
