Iran Vows Retaliation for Khamenei's Killing; Trump Dismisses Threats Amid Escalation

Iran's security chief Ali Larijani has vowed retaliation against US President Donald Trump for the killing of Supreme Leader Ayatollah Ali Khamenei in a US-Israeli strike on February 28, warning Trump will "pay the price" and that Iran will not relent until it has reciprocated. Larijani accused Trump of miscalculating Iran's response and warned neighboring countries against allowing US attacks from their territories. Trump dismissed Larijani's threats, stating he "couldn't care less" and demanding Iran's unconditional surrender as the conflict escalates in the Middle East.
