Fresh fears have been raised that the globe could be heading towards World War 3 after Iran warned it will "destroy" US warships if threatened in the Persian Gulf.
US President Donald Trump tweeted on Wednesday to say: "I have instructed the United States Navy to shoot down and destroy any and all Iranian gunboats if they harass our ships at sea." In response to Trump's tweet, Major General Hossein Salami said on Iranian state TV: "I have ordered our naval forces to destroy any American terrorist force in the Persian Gulf." The exchange led many Twitter users to raise fresh fears that WW3 could be on the way as a result of rising tension between the aggressive nations.
