DUBAI, United Arab Emirates -- Iran's Revolutionary Guard navy issued a stark warning on Saturday, stating that any strikes on its oil tankers or commercial ships would provoke a "heavy assault" against U.S. bases in the region and hostile vessels, while a fragile ceasefire continues to hold.

State television in Iran broadcast the alert one day after U.S. forces hit two Iranian oil tankers, raising questions about the month-long ceasefire that American officials maintain remains active. The U.S. military explained that the tankers attempted to violate its naval blockade around Iran's ports.

In related developments, Bahrain - home to the U.S. Navy's key regional command - announced the detention of dozens of individuals accused of ties to Iran's Revolutionary Guard.

Washington is monitoring Tehran's reply to its newest offer for a pact to conclude the conflict, restore access to the Strait of Hormuz for maritime traffic, and curb Iran's controversial nuclear activities. Russian President Vladimir Putin noted that Moscow's plan to manage Iran's enriched uranium stocks as part of talks is still available.

Authorities in Bahrain reported capturing 41 suspects linked to a network connected with the Revolutionary Guard. The interior ministry indicated that probes verified their communications with the Guard and fundraising efforts "intended for transfer to Iran" to finance "terrorist activities."

This tiny Persian Gulf nation, governed by a Sunni royal family, shares a Shiite majority with Iran. Human rights organizations claim Bahrain has exploited the U.S.-Iran war - with the U.S. Fifth Fleet stationed there - to suppress opposition voices.

Iran delivered a direct message to Bahrain: "Aligning with the U.S.-supported measures will invite dire repercussions. The Strait of Hormuz serves as a crucial artery; avoid endangering its passage indefinitely," declared Ebrahim Azizi, chairman of Iran's parliamentary national security committee, via social media.

Since the U.S. and Israel initiated hostilities on February 28, Iran has largely sealed off this essential global energy route, driving up fuel costs worldwide and unsettling financial markets.

The United States has enforced a counter-blockade on Iranian harbors. U.S. Central Command reported Saturday that its units repelled 58 merchant vessels and neutralized four others since the operation started on April 13.

Britain's defense ministry announced the dispatch of a warship to the Middle East to support future efforts safeguarding commercial shipping in the Strait of Hormuz after fighting subsides.

The HMS Dragon will position itself nearby to participate in a security initiative led by the U.K. and France. France revealed earlier this week its deployment of an aircraft carrier group to the Red Sea as a precaution.

London and Paris have coordinated discussions with numerous nations to form a coalition ensuring safe passage through the strait. They emphasize operations will commence only after a lasting truce and confidence returns to the shipping sector.

U.S. President Donald Trump renewed warnings of escalating airstrikes should Iran reject terms to unlock the strait and dismantle its nuclear pursuits. Iran's foreign ministry spokesman Esmail Baghaei dismissed such timelines on Friday, per the official IRNA news agency.

Diplomatic channels stay open. Pakistan's Prime Minister Shehbaz Sharif revealed ongoing round-the-clock engagement with Washington and Tehran to prolong the truce and secure lasting peace.

Russia's foreign ministry, alongside Saudi Arabia, urged intensified talks for a "durable, comprehensive accord" to resolve the war.

Putin, speaking to journalists in Moscow, explained that transferring Iran's enriched uranium for oversight would reveal its quantities and sites, all monitored by the IAEA, the United Nations nuclear authority.

Senior Egyptian and Qatari envoys affirmed diplomacy as the only viable resolution, based on their recent phone discussion.

Iran's newly appointed Supreme Leader Mojtaba Khamenei has remained out of public view since the conflict's outset, sparking rumors about his condition.

A senior Iranian figure assured on Friday that Khamenei enjoys "full health" and will soon appear publicly. Mazaher Hosseini, linked to the office of the late Ayatollah Ali Khamenei - slain in the war's initial phase - shared this at a regime-support rally. He noted Mojtaba sustained knee and back wounds from early assaults but has recovered substantially.
