Strait of Hormuz blockade disrupts energy supplies and shipping
Reports describe the Strait of Hormuz as blocked or restricted during the US-Iran war, disrupting energy flows and contributing to pressure on oil and gas markets. Several accounts attribute the closure to Iranian action; the BBC says Iranian attacks on commercial vessels and a US blockade had together effectively closed the strait.
