The US has bombed three Iranian nuclear sites, with President Trump claiming the strikes took the bomb out of Iran's hands. Iran's President says the US must receive a response for their aggression, while the UN's nuclear watchdog is unable to assess the damage at one of the sites. The US and Israel have been working to counter Iran's nuclear ambitions for decades, with Israel saying the world should thank Trump for acting. The situation has sparked concerns about a potential nuclear arms race in the Middle East.
