Attack on the Namu and Immediate Aftermath
On 4 May 2026, the South Korean bulk carrier Namu, operated by HMM, was struck near its stern by two unidentified objects while transiting the Strait of Hormuz. South Korean authorities later said the damage matched an anti-ship missile, initially pointing to an Iranian system. The impact left the vessel immobilised with 35 crew members aboard, joining a second South Korean ship also stranded in the waterway.
Background: Regional Tensions in the Strait
The attack came after the United States and Israel launched attacks on Iran on 28 February, prompting Tehran to close the Strait of Hormuz and driving up oil prices. A cease-fire between Washington and Tehran was signed two weeks before 1 July, after which 21 South Korean-operated vessels have safely transited the waterway.
Timeline of Developments
- 4 May – Namu struck near stern, immobilised.
- 27 May – South Korea cited a probable Iranian anti-ship missile and summoned Iran’s ambassador.
- 1 July – Oceans Ministry announced Namu would leave the strait in mid-July after repairs.
Data and Statistics
- 35 crew members remain on board Namu.
- Two South Korean vessels are currently stranded in the strait.
- 21 South Korean-operated ships have passed safely since the cease-fire.
- HMM is covering repair costs and will file an insurance claim.
Official Statements & Responses
The Oceans Ministry said the repaired Namu will leave the strait at the earliest in mid-July. Vice Minister Nam Jae-heon indicated that South Korea could later review compensation claims against Iran or the United States. HMM confirmed it is financing the repairs and will seek reimbursement through its insurer. Iran’s ambassador Saeed Koozechi categorically denied Tehran’s involvement in the attack.
Criticism & Opposition
Iran’s denial directly challenges South Korea’s initial attribution to an Iranian missile, highlighting diplomatic friction and differing interpretations of the incident.
Conflicting Reports & Gaps
South Korean officials first identified a probable Iranian missile but later admitted they could not conclusively determine the responsible party or whether the strike was intentional. No independent investigation results have been released, leaving the identity of the two objects unresolved.
Verbatim Quotes

Why It Matters
The episode underscores the vulnerability of commercial shipping to geopolitical conflict in a critical chokepoint. Uncertainty over liability and repair costs may influence future insurance rates, routing decisions, and the stability of global oil supplies.
What’s Next
Namu is scheduled to depart the Strait of Hormuz in mid-July after final safety checks. South Korea’s possible review of compensation claims suggests further diplomatic dialogue with Iran and the United States.
