US President Donald Trump on Sunday warned Iran against striking US targets saying that if they do "We will hit them with a force that has never been seen before.""Iran just stated that they are going to hit very hard today, harder than they have ever been hit before. THEY BETTER NOT DO THAT, HOWEVER, BECAUSE IF THEY DO, WE WILL HIT THEM WITH A FORCE THAT HAS NEVER BEEN SEEN BEFORE! Thank you for your attention to this matter! President DONALD J. TRUMP," Trump said in a post on Truth Social.
