US President Donald Trump has announced a blockade of the Strait of Hormuz, a vital maritime route, after peace talks with Iran in Islamabad, Pakistan, ended without agreement. The negotiations, which lasted 21 hours, aimed to address Iran's nuclear weapons program, a key point of contention. Trump threatened to bomb Iran's water treatment facilities and power plants if Tehran does not comply. The Iranian Revolutionary Guards responded firmly, stating that any US military presence in the strait would be viewed as an act of war. The blockade is expected to escalate tensions further, risking an increase in oil prices as the US Navy is directed to intercept vessels that have paid tolls to Iran. The conflict, which has seen US and Israeli strikes on Iran, has already resulted in thousands of casualties across the Middle East, and the situation remains volatile as both sides seek to navigate this complex geopolitical landscape.
