Attack Risks Rise for Tankers as Iran Vows to Block More Hormuz Routes

Iran has warned regional countries that any attempt to open new routes for oil exports would be considered hostile, according to a senior regional official. Tankers face a higher risk of attacks and intimidation in the Strait of Hormuz, and last week saw the largest number of attacks on tankers there since the Iran war began, reducing transiting vessels to a more than two-month low. In the latest incident, projectiles struck the Antigua and Barbuda-flagged chemical tanker Acers north of Qatar's Madinat ash Shamal, causing minor injuries.

Why it matters: The threat to Hormuz shipping bears directly on energy security, as attacks and route closures risk disrupting global oil supply and prices.
