Iran threatens retaliation after US strikes kill 50, injure 500

Iran has threatened a proportionate response against nations hosting US forces, following a week of US airstrikes that killed at least 50 people and injured 500, according to Iran's Health Ministry. Two US soldiers were killed in an Iranian attack, and Supreme Leader Ayatollah Khamenei warned of 'unforgettable lessons,' calling President Trump's signature 'worthless.' Iran has also threatened a 'full-scale' offensive if the US continues bombing, while Khamenei is reportedly avoiding public appearances until the conflict ends.
