The Iranian navy has issued a stern warning to vessels near the Strait of Hormuz, stating that they must obtain permission from the Iranian Sepah navy to cross. Any ship that attempts to transit without this authorization will be destroyed. This warning comes in the wake of a temporary ceasefire agreement between the United States and Iran, where U.S. President Donald Trump announced a two-week pause on military strikes against Iran, contingent on the reopening of the strait in a safe manner. The Strait of Hormuz, a narrow waterway only 34 kilometers (21 miles) wide, is a vital passage for global oil supplies, accounting for approximately 20% of the world's oil transport. The U.S. has reported that many ships are currently stationary in the strait, and tensions remain high with military aircraft still active over the Persian Gulf. Trump's announcement of the ceasefire followed diplomatic proposals from Pakistan's Prime Minister Shehbaz Sharif.
