Iran Re-Closes Strait of Hormuz, Fires on Merchant Vessels amid U.S. Blockade
Tehran reinstates total maritime blockade following U.S. naval operations, prompting a sharp diplomatic protest from India.
On April 18, 2026, Iranian forces fully re-closed the Strait of Hormuz, marking a sharp reversal from a temporary reopening just one day prior. The Iranian Revolutionary Guard has implemented a "strict management and control" policy, enforcing the closure with gunboats and firing warning shots at maritime traffic. One container vessel was reportedly damaged by a projectile, while two Indian-flagged ships were targeted, leading New Delhi to summon the Iranian ambassador in a formal diplomatic protest.
The escalation comes in direct response to a U.S. naval blockade of Iranian ports. U.S. Central Command confirmed that its forces have intercepted and turned back 23 ships since Monday. While Iranian Supreme Leader Ayatollah Mustafa Khamenei warned of a "full force" response to continued U.S. pressure, President Donald Trump maintained that the U.S. would not be swayed by maritime disruptions. Despite the tension, Pakistani mediators are working to bridge the gap between Washington and Tehran, with a new round of talks expected next week.
The sudden reinstatement of the blockade has heightened concerns over global energy security and the stability of the fragile U.S.-brokered ceasefire between Israel and Hezbollah. Iranian officials have accused the Trump administration of risking the global economy, while U.S. officials maintain that the pressure campaign is necessary to prevent Iranian nuclear proliferation and regional aggression.
