Trump issues apocalyptic Iran ultimatum

U.S. President Donald Trump has dramatically escalated his rhetoric against Tehran, setting a strict Tuesday deadline for the reopening of the strategic Strait of Hormuz.

In an expletive-filled social media tirade, the president warned that failure to comply would result in the total destruction of Iran's civilian infrastructure, including its power grid and major bridges.

Iranian officials have dismissed the ultimatum as an incitement to war crimes, vowing a devastating retaliatory response if targeted.
