Iran says it is closing the Strait of Hormuz again to commercial vessels and that any ship that approaches it will be targeted. The closure came as reports emerged of vessels in or near the strait, including a tanker, being targeted by Tehran. The Islamic Revolution Guard Corps (IRGC) blamed a continuing US blockade for its decision, which comes a day after Iran's foreign minister announced the key global shipping channel had been temporarily reopened. US President Donald Trump stated that Iran cannot 'blackmail' the US with threats regarding the waterway, which Tehran has effectively blocked for nearly two months, causing global energy prices to soar. The IRGC Navy warned that 'no vessel is to move from its anchorage in the Persian Gulf or the Sea of Oman.' They have maintained that while some vessels passed through the strait, it will shut again until the US ends its blockade of Iranian ports. Further threats include labeling those approaching the strait as cooperating with the enemy, thereby subjecting offending vessels to targeting. As the US has reportedly turned away multiple ships due to the blockade, tensions are high, reflecting the ongoing conflict since recent military actions commenced on February 28, leading to instability in oil transport routes which account for about 20% of the world's oil transportation.
