Trump issues final Iran ultimatum

Tensions in the Middle East have reached a critical flashpoint as President Trump doubled down on his threat to decimate Iran's civilian infrastructure.

The ultimatum requires Tehran to reopen the vital Strait of Hormuz energy artery by 8 p.m. ET on Tuesday or face a massive four-hour bombardment.

While Trump claims active peace talks are underway via Pakistani intermediaries, Tehran has publicly rejected a 45-day ceasefire proposal.

Experts and international observers have warned that targeting power plants and bridges could constitute war crimes under international law.
