President Donald Trump says he is holding off on a military strike on Iran planned for Tuesday because “serious negotiations” are underway. Trump’s announcement in a social media post Monday came as he had threated the clock was ticking for Iran to strike a deal or fighting would renew after a fragile ceasefire. The president did not offer details about the planned attack but said but he instructed the U.S. military “to be prepared to go forward with a full, large scale assault of Iran, on a moment’s notice, in the event that an acceptable Deal is not reached.”
