24 more vessels traverse Hormuz under IRGC supervision
Iran's Islamic Revolution Guards Corps (IRGC) Navy said on Tuesday that 24 commercial vessels had transited the Strait of Hormuz over the past 24 hours after obtaining permission and receiving security coordination from the force.
The announcement, carried by Iran's Tasnim news agency, comes as Tehran continues to assert control over the strategic waterway amid heightened military tensions with the United States and Israel.
"Smart control of the Strait of Hormuz is being carried out with authority, and malevolent foreigners will have no place in the Persian Gulf and the Strait of Hormuz," the IRGC Navy said in a statement.
The Islamic Republic has tightened oversight of shipping through the strait – a vital chokepoint for global oil flows – since the outbreak of armed conflict on February 28. Iran’s southern ports also remain under a US naval blockade, which President Donald Trump imposed in mid-April, aiming to pressure Tehran into a peace agreement after the 40-day conflict.
Iranian authorities require commercial vessels to obtain permits and coordinate with the IRGC before transiting, often routing them through a northern corridor inside Iranian territorial waters.
Iran has defined a supervisory management zone over the Strait of Hormuz, requiring coordination and permits for passage. The zone was described as “the line connecting Mount Mubarak in Iran and southern Fujairah in the United Arab Emirates, on the eastern side of the strait, extending to the line connecting the end of Qeshm Island in Iran and Umm Al Quwain in the United Arab Emirates, on the western side of the strait.”
The 24 ships were among dozens of vessels that transited the strait under Iranian permission since last month, though total crossings in April 2026 reached just 191 vessels — roughly 5% of the pre-war monthly average of around 3,600 transits.
Shipping traffic has collapsed compared with pre-conflict levels. According to maritime intelligence firm Windward, the strait historically handled approximately 120 transits per day in both directions before the war. As of late May, that figure has fallen to roughly seven transits per day – a decline of about 94%.
