US Tightens Naval Blockade As Tehran Warns Of 'Heavy Assault' In Strait Of Hormuz | Top Points

Last Updated:May 10, 2026, 09:49 IST

The US-Iran conflict intensified around the Strait of Hormuz as Washington tightened its naval blockade, claiming it had redirected 58 commercial vessel.

The United States’ naval blockade against Iran emerged as the biggest flashpoint in the ongoing conflict, with US Central Command confirming that American forces had redirected 58 commercial vessels and “disabled" four ships since April 13 to stop movement in and out of Iranian ports.

The blockade has become Washington’s key pressure tactic as it pushes Tehran to reopen the Strait of Hormuz and return to negotiations.

The latest escalation came after the US military struck two Iranian-linked vessels that it said were attempting to breach the blockade and enter an Iranian port.

According to AP, a US fighter jet hit the vessels’ smokestacks, forcing them to retreat. The incident has further strained the month-old ceasefire that Washington insists is still technically holding.

Iran responded with sharp warnings, with the Revolutionary Guard navy declaring that any attack on Iranian oil tankers or commercial vessels would trigger a “heavy assault" on one of the US bases in the region and on “enemy ships."

The threat underscored growing fears that the fragile calm around the Strait of Hormuz could collapse into a wider confrontation.

• AP reported that Iran has largely blocked the Strait of Hormuz since the US and Israel launched the war on February 28, causing global fuel prices to spike and rattling international markets. Reuters noted that before the conflict, nearly one-fifth of the world’s oil supply passed through the narrow waterway.
• Despite recent flare-ups, Reuters reported that “a state of relative calm prevailed around the Strait of Hormuz" on Saturday as Washington awaited Tehran’s response to a fresh US proposal aimed at ending more than two months of fighting and initiating peace talks.
• US Secretary of State Marco Rubio said Washington expected a response from Iran “within hours." However, Reuters reported there was still “no sign of movement" from Tehran a day later.
• Reuters said Rubio met Qatari Prime Minister Mohammed bin Abdulrahman al-Thani in Miami, where both sides discussed the need “to deter threats and promote stability and security across the Middle East." The US statement did not specifically mention Iran.
• Diplomatic efforts intensified on multiple fronts. Pakistani Prime Minister Shehbaz Sharif said Islamabad had been in touch with both Washington and Tehran “day and night" to preserve the ceasefire and secure a peace agreement.
• Russian President Vladimir Putin said Moscow’s proposal to take enriched uranium from Iran remained under discussion. Putin said the arrangement would allow the international community to know “how much of it there is, and where it is located," while ensuring that “all of this would be placed under the control of the IAEA."
• Bahrain, which hosts the US Navy’s Fifth Fleet headquarters, announced the arrest of 41 individuals allegedly linked to Iran’s Revolutionary Guard. Bahraini authorities claimed the group was collecting funds to support Iran’s “terrorist operations."
• Iran responded with a warning directed at Bahrain. Ebrahim Azizi, head of the Iranian parliament’s national security commission, wrote on social media, “Siding with the US-backed resolution will bring severe consequences. The Strait of Hormuz is a vital lifeline; do not risk closing it on yourselves FOREVER."
• Britain announced the deployment of the HMS Dragon warship to the Middle East in preparation for a possible multinational mission to secure commercial shipping routes through the Strait of Hormuz once hostilities subside. France has also moved its aircraft carrier strike group into the Red Sea.
• Britain and France have reportedly led discussions involving several dozen countries on restoring freedom of navigation through the strait. However, both countries stressed that any mission would only begin once there is a “sustainable ceasefire" and commercial shipping companies feel safe returning to the route.
• Reuters reported that clashes extended beyond the strait, with the United Arab Emirates saying its air defences intercepted two ballistic missiles and three drones launched from Iran on Friday. Three people reportedly sustained moderate injuries.
• Iranian Foreign Minister Abbas Araqchi accused Washington of undermining diplomacy, saying, “Every time a diplomatic solution is on the table, the US opts for a reckless military adventure."
• Reuters reported that the US Treasury also imposed sanctions on 10 individuals and companies, including entities in China and Hong Kong, accusing them of helping Iran secure materials tied to the production of Shahed drones.
• In a potentially significant development, a Qatari liquefied natural gas tanker sailed toward the Strait of Hormuz en route to Pakistan. Reuters, citing sources, reported that Iran approved the transit as a confidence-building gesture toward Qatar and Pakistan, both of which have acted as mediators in the conflict. If successful, it would mark the first transit of a Qatari LNG vessel through the strait since the war began.

Even as diplomatic channels remain active, the latest confrontations around the Strait of Hormuz have exposed the fragility of the ceasefire between Washington and Tehran.

The US naval blockade, Iran’s threats against regional bases, and continuing clashes at sea have kept energy markets and global shipping routes on edge.

At the same time, international powers including Russia, Qatar, Pakistan, Britain and France are intensifying efforts to prevent the conflict from spiralling further.

With Washington waiting for Tehran’s formal response to its latest proposal, the coming days are expected to determine whether the region moves toward negotiations or a renewed escalation in one of the world’s most strategically sensitive waterways.
