History

Historical Context

On 13 June 2019 IRGC-linked limpet mines damaged the Japanese tanker Kokuka Courageous and ignited the Norwegian-owned Front Altair in the Gulf of Oman, marking the first major maritime strike attributed to Iran. Subsequent IRGC actions—including the July 2021 drone hit on the Liberian-flagged MT Mercer Street and the November 2022 drone attack on Pacific Zircon—establish a pattern that underpins today’s threat to close the Strait of Hormuz.
