Tensions in the Strait of Hormuz escalated sharply when Iran fired on a commercial tanker and reimposed restrictions on the vital waterway, which handles 20% of global oil shipments. US President Donald Trump emphasized that Iran cannot blackmail the US and confirmed that the naval blockade against Iran will remain in place until a deal is reached, particularly regarding its nuclear program. In a significant escalation, the US military is preparing to board and seize Iran-linked vessels globally, with 23 ships already turned back since the blockade began. Diplomatic efforts are ongoing, with Pakistan mediating talks between the US and Iran as a ceasefire deadline approaches on April 22. Iran's Supreme National Security Council stated it would maintain control over the Strait of Hormuz until lasting peace is achieved and warned that the strait would not fully reopen unless the US lifts its blockade.
