Iran has intensified its claims over the strategically vital Strait of Hormuz, asserting military control over an expanded area that now encompasses over 22,000 square kilometres (8,800 square miles). This assertion comes from Iran’s newly established “Persian Gulf Strait Authority,” which has sparked immediate backlash from regional stakeholders, particularly the United Arab Emirates (UAE). The situation is further complicated by recent military activities from the United States in the region, including the boarding of an oil tanker suspected of breaching an American blockade on Iranian ports.
Iran’s Expanding Claims
The Iranian government has issued a new map indicating its oversight of the waters surrounding the Strait of Hormuz, a critical passage for global oil transport. This declaration extends into the territorial waters of both Oman and the UAE, leading the latter to dismiss Iran’s claims as mere “fragments of dreams.” Anwar Gargash, a senior diplomatic advisor to the UAE president, expressed strong disapproval, stating that Iran is attempting to establish a reality based on military failure rather than legal grounds.
The Iranian authority has stated that any vessel wishing to transit the strait must now seek permission from its office. This move appears to be an effort to solidify Iran’s regional influence, but it faces staunch opposition from both the US and its Gulf allies, who have consistently denied Iran’s legitimacy in asserting control over this vital maritime route.
Recent Military Incidents
In a related development, Iranian state media, linked to the Islamic Revolutionary Guard Corps (IRGC), released footage purportedly showing a “punishment” strike on a tanker within the strait. Analysis from BBC Verify suggests that the vessel shown in the footage correlates with the Barakah, a Liberian-flagged tanker that reported being struck by unidentified projectiles earlier this year.
These tensions escalated further when US Central Command (Centcom) announced the boarding of an Iranian-bound oil tanker, the Celestial Sea, suspected of attempting to breach the US-imposed blockade. Footage released by Centcom illustrated US Marines descending onto the vessel, which had previously faced sanctions due to its ties with Iran. Following a search, the ship was directed to change course towards the port of Duqm in Oman.
Diplomatic Efforts and Regional Responses
The United States has taken a firm stance against Iran’s attempts to exert influence over the strait, with Centcom reporting that it has redirected 94 commercial vessels and disabled four ships since the blockade took effect on 13 April. In a notable diplomatic gesture, US President Donald Trump announced he would delay a planned military strike on Iran, indicating that serious negotiations were underway, as requested by leaders from Qatar, Saudi Arabia, and the UAE.
Concurrently, Pakistan’s military chief, Asim Munir, is visiting Tehran to facilitate peace discussions between Iran and the US. The Iranian foreign ministry has confirmed that it is considering the latest US proposals aimed at resolving ongoing conflicts, suggesting a possible shift in the tense dynamics of the region.
Why it Matters
The situation in the Strait of Hormuz is emblematic of broader geopolitical tensions, where control over vital maritime routes intersects with national sovereignty and international law. Iran’s expanded claims not only challenge existing maritime agreements but also threaten the stability of global oil markets, given that a significant percentage of the world’s oil passes through this narrow passage. The ongoing military and diplomatic maneuvers underscore the fragile balance of power in the region, making it imperative for all parties to navigate these waters with caution to avoid further escalation.
