Iran Closes Strait of Hormuz Again Amid US Blockade, Fires on Ships as Tensions Escalate

In a major escalation of the Iran-US conflict on April 18, 2026, Iran announced it has closed the Strait of Hormuz again, halting ship movement and firing on vessels, in response to a continued US blockade on Iranian ports.

The renewed Strait of Hormuz crisis has raised global concerns as the waterway handles nearly one-fifth of the world’s oil supply, making it critical to the global economy.

What Happened: Iran Blocks Strait of Hormuz and Targets Ships

According to Iranian military authorities:

• Iran has placed the Strait of Hormuz under strict control of its armed forces
• Shipping through the route is being blocked until the US lifts its blockade
• Iranian forces opened fire on a tanker attempting to pass
• A container ship was hit by a projectile, causing damage

Reports indicate that two Indian-flagged vessels, including a supertanker carrying Iraqi oil, were forced to turn back after the incident.

Why Strait of Hormuz Is Critical to Global Economy

The Strait of Hormuz is one of the world’s most important maritime routes:

• Carries around 20% of global oil trade
• Connects the Persian Gulf to international markets
• Any disruption can trigger fuel price spikes and economic instability

The latest closure has intensified fears of a global energy crisis.

Iran’s Position: No Talks Until US Ends Blockade

Iran’s Deputy Foreign Minister Saeed Khatibzadeh stated that:

• Iran will not resume talks with the United States unless conditions change
• The US blockade is a major threat to the ceasefire
• Iran will continue to protect its sovereignty and economic interests

Iranian leadership also signaled strong military readiness. Supreme Leader Mojtaba Khamenei said the navy is prepared to inflict strong retaliation against enemies.

US Response and Military Pressure Continues

The United States has maintained its blockade on Iranian ports, aiming to pressure Tehran during ongoing negotiations.

• US Central Command reported 21 ships were turned back since the blockade began
• Naval deployments continue across West Asia waters
• The blockade remains active despite the earlier reopening of the strait

Diplomatic Efforts: Pakistan Mediating Talks

Efforts are underway to reduce tensions:

• Ishaq Dar confirmed Pakistan is trying to mediate between Iran and the US
• Talks are expected to take place soon to extend the ceasefire
• However, Iran has expressed reluctance for direct negotiations at this stage

Strait of Hormuz Closure Triggers Global Alarm

The closure of the Strait of Hormuz by Iran amid the US blockade marks a serious escalation in the conflict. With ships being targeted and oil routes disrupted, the crisis threatens global energy security and economic stability, while diplomatic efforts continue to prevent further escalation.
