Source material: Trump warns against ‘blackmail' as Iran closes Strait of Hormuz again
Summary
President Trump has warned Iran against 'blackmail' after Tehran closed the Strait of Hormuz again, following a U.S. naval blockade of its ports. Iranian gunboats have reportedly attacked at least two cargo ships in the Strait since its closure, complicating any potential negotiations with Tehran. The U.S. military noted that 23 ships complied with the blockade and returned to Iran, further straining diplomatic relations. Iran maintains that its enriched uranium will not be sent to the U.S. or other countries, despite stalled peace talks. The ongoing situation in the Middle East is disrupting global trade, prompting discussions among the International Monetary Fund and World Bank. Recent incidents involving UN personnel in Gaza have raised concerns about accountability and potential war crimes amid a fragile ceasefire. The closure of the Strait of Hormuz has led to an estimated loss of 900 million barrels of oil, severely affecting both advanced economies and vulnerable populations in Asia. Countries like India, Bangladesh, and Myanmar are experiencing significant energy shortages, prompting drastic measures such as using firewood for heating and halting public transport.
