US President Donald Trump has vowed to launch tougher economic measures against Iran and any country helping it, describing it as a "crushing economic operation ever taken against any country". The move comes after a 60-day ceasefire expired without a diplomatic settlement in the war between the US and Israel. Trump's threat was made on social media platform Truth Social, where he also announced that countries providing financial support to Iran would face "TREMENDOUS Economic Consequences", but did not specify what punishment they might face. The UAE has already severed all financial and economic ties with Iran in response to a new missile threat from the country.
