Iran's Islamic Revolutionary Guard Corps (IRGC) has claimed responsibility for at least one of three strikes on civilian ships in the Strait of Hormuz, according to the United Kingdom Maritime Trade Operations (UKMTO) Operations Centre. The ships, later identified as a Thai cargo vessel and three crew members missing, were reportedly fired upon by Iranian fighters. The IRGC has not yet claimed the other two strikes. The strike occurred at a critical time for the global oil trade, affecting an average of 20 million barrels of oil per day and accounting for 25% of global seaborne oil trade.
