Iran Closes Strait of Hormuz to All Vessels After Clashes With U.S. Forces

Iranian and U.S. forces clashed in the Gulf and Gulf of Oman on Thursday after Iran announced the full closure of the Strait of Hormuz to all vessels.

Clashes Erupt Between Iranian and U.S. Forces

Initial reports indicated that U.S. ships near the Strait of Hormuz were targeted by missiles and drones launched by Iranian armed forces. [1] Blasts were also heard in the counties of Sirik and Minab and the port city of Bandar Abbas, all in Hormozgan province, as well as on Qeshm and Hengam islands. [1] Air defense systems were activated west of the capital Tehran and in the southern province of Fars, according to the semi-official Mehr news agency. [1] These events marked the start of direct confrontations in the waters of the Gulf and the Gulf of Oman early on Thursday. [1] The sequence of missile and drone activity against U.S. vessels occurred amid heightened tensions that had already prompted defensive measures from American forces in the region. [1] Reports from the area described the activation of Iranian air defenses as a direct response to the unfolding incidents near the strategic waterway. [1]

Iran Announces Full Closure of Strait of Hormuz

Following the incidents, Khatam al-Anbiya Central Headquarters said the Strait of Hormuz has been closed to all kinds of vessels, including oil tankers and commercial ships, owing to security threats in the waterway. [1] The headquarters cited the continuation of the U.S. "malicious acts" and attacks earlier in the day in Iran's southern Hormozgan province, saying any vessel trying to pass through the strait will be targeted. [1] This announcement came directly from Iran's main military command and applied the closure to every type of vessel attempting transit. [1] The decision reflected the command's assessment of ongoing threats that had escalated through the reported attacks in Hormozgan province. [1] Officials emphasized that the full closure would remain in effect to counter the identified security risks along the waterway. [1]

U.S. Central Command Response

The developments followed an announcement by the U.S. Central Command on social media platform X, stating its forces had begun launching "additional self-defense strikes" against multiple targets in Iran in response to what it called Iran's "unwarranted and continued aggression." [1] This U.S. statement preceded the Iranian closure announcement and framed the strikes as measures taken to address prior aggression. [1] The sequence showed the American action as a trigger point that immediately preceded the Iranian military command's decision to shut the strait. [1] Central Command described the strikes as self-defense operations aimed at multiple locations inside Iran. [1]

Impact on Shipping in the Strait

This photo taken with a mobile phone shows merchant vessels stranded in the waters of the Strait of Hormuz, near Khasab, a small town in northern Oman, May 29, 2026. [1] Visual evidence captured merchant vessels left unable to proceed through the waterway following the closure announcement. [1] The presence of these stranded ships near Khasab illustrated the immediate effect on commercial traffic attempting to navigate the strait. [1] The image from May 29, 2026, provided a record of vessels halted in the area amid the security measures. [1]

Broader Regional Context

With heavyweight Middle East wars going on in Lebanon and Iran, the low-intensity continual takeover of the West Bank by Israel hardly makes a ripple on the world geopolitical scene. [2] The Israeli government has unleashed multiple weapons to subdue the West Bank, a territory long coveted by Israeli expansionists as the key to creating a Greater Israel between the Jordan River and Mediterranean. [2] The Israeli public seems okay with the takeover so long as it doesn’t reach formal annexation. [2] These actions run parallel to the more intense conflicts elsewhere in the region, including those involving Iran. [2] The situation in the West Bank has continued as a lower-intensity conflict alongside the wars in Lebanon and Iran. [2]

What to watch next: Observers will monitor whether the closure of the Strait of Hormuz leads to further vessel strandings or additional military responses from either side, as the parallel low-intensity developments in the West Bank continue amid the wider regional wars.
