Iran Closes Strait of Hormuz Again, Fires on Ships Amid US Standoff; Indian Tankers Caught in Crossfire

Dubai/New Delhi — April 19, 2026

Iran has once again shut down the strategically vital Strait of Hormuz, escalating tensions with the United States and triggering fresh concerns over global oil supply disruptions.

The naval wing of Iran’s Islamic Revolutionary Guard Corps (IRGC) announced on April 18 that it has imposed “strict control” over the strait and halted commercial shipping until the US lifts its blockade of Iranian ports.

Gunfire Reported as Ships Attempt Transit

The IRGC warned that any vessel attempting to pass through the strait would be treated as cooperating with the enemy and could be targeted.

Shipping sources and the UK Maritime Trade Operations confirmed that Iranian gunboats opened fire on multiple merchant vessels northeast of Oman. While damage was reported as minor, no casualties among crew members have been confirmed.

Indian Tankers Among Affected Vessels

Several India-linked ships were caught in the unfolding crisis. Reports indicate that Iranian forces fired upon Indian-flagged tankers, including Sanmar Herald, while another vessel remained unidentified.

One oil tanker, Desh Garima, successfully crossed the strait amid the tension, becoming one of the few vessels to transit during the disruption. Others reportedly turned back due to safety concerns.

India’s Foreign Secretary Vikram Misri summoned Iran’s ambassador to express “deep concern” over the incidents involving India-bound energy shipments.

Global Oil Supply at Risk

The Strait of Hormuz is one of the world’s most critical energy corridors, handling around 20% of global oil trade. Any disruption in the region has immediate implications for global energy markets.

Analysts warn that a prolonged closure could lead to:

• Sharp spikes in global oil prices
• Delays in supply chains
• Increased shipping and insurance costs
• Economic ripple effects across energy-dependent economies
• Escalation After Diplomatic Breakdown

The latest escalation comes less than a day after Iran’s Foreign Minister Abbas Araghchi had stated that the strait remained open.

The reversal follows stalled negotiations between Tehran and Washington, with the United States maintaining its naval blockade until a broader agreement is reached.

The ongoing standoff underscores the fragile security situation in the region and the potential for further escalation.

Strategic and Security Implications

Experts believe the situation could:

• Increase military presence in the Gulf region
• Heighten risks for commercial shipping
• Force countries like India to explore alternative energy routes
• Trigger broader geopolitical tensions
