Iran's claim of foreign ship stuck in Strait of Hormuz disputed as vessel linked to Tehran official

Following the outbreak of the US-Israeli war with Iran on February 28, 2026, which killed Supreme Leader Ayatollah Ali Khamenei, Tehran paralyzed the Strait of Hormuz to leverage global energy markets. While a recent US-Iran memorandum of understanding has enabled a fragile, partial reopening of the waterway, Iran continues to assert control. This is highlighted by disputed state media claims of a grounded foreign ship, which independent trackers identified as the Arista, a vessel linked to sanctioned Iranian oil tycoon Mohammad Hossein Shamkhani.
