US President Donald Trump has said that any new nuclear facilities that Iran decides to build will be destroyed, while doubling down on the administration's claim that America's military strikes "completely destroyed" three nuclear sites in the West Asian country in June.

Launching from deep within the United States, B-2 stealth bombers dropped a staggering 420,000 pounds of ordnance, supported by a fleet of refueling tankers and fighter jets, some of which fired their own munitions.

Donald Trump has threatened to bomb Iran again in a fresh warning over the rebuilding of the country's nuclear sites. The US President issued the stark warning following what he claims was the complete destruction of three existing sites last month.
