The United States and Iranian militaries exchanged fire early Tuesday, hours after President Trump threatened to reimpose a naval blockade and begin charging a 20 percent toll on vessels transiting the Strait of Hormuz, according to The Hill. The escalation marks a significant deterioration in the region, where renewed fighting over the past week has dashed hopes for a return to normality in the strategically vital waterway.

Military Exchange and Blockade Threat

According to The Hill, President Trump announced on Monday that the US military would reimpose its naval blockade in the Strait of Hormuz and begin charging a 20 percent toll on vessels transiting the channel immediately. The critical trading passage, through which about one-fifth of global energy passes in peacetime, has been a flashpoint in US-Iran tensions for months. Early Tuesday, the US and Iranian militaries exchanged fire, though details of the engagement remain limited.

Iranian Parliamentary Response

In Tehran, hardline lawmakers tabled a new plan for the management of the Strait of Hormuz during an unannounced parliamentary session on Monday night, as reported by Al Jazeera. The motion, titled the Strategic Action for the Security and Sustainable Progress of the Strait of Hormuz and the Persian Gulf, could be debated or passed during future sessions. The official text has not been publicly divulged, but an earlier draft published by state media in May indicated that vessels flying US or Israeli flags would be barred from passage, along with military or hostile vessels. All vessels would need permits, disclose cargo, and pay fees, with violators facing blocked passage or confiscation of up to 20 percent of cargo value, with revenues going to the military and infrastructure reconstruction.

Ebrahim Azizi, head of the national security commission of parliament, wrote on social media that the plan is the first step and subsequent measures are forthcoming. The hardline-dominated parliament reconvened after nearly five months of confrontation with the US, with lawmakers waving religion-based red flags of vengeance for Supreme Leader Ayatollah Ali Khamenei and other top officials killed on the first day of the war launched by the US and Israel on February 28.

Why It Matters

The Strait of Hormuz is a chokepoint for global energy supplies, and any disruption could have severe economic consequences. The renewed fighting over the past week has put at risk a memorandum of understanding signed by the US and Iran last month, which had raised hopes for de-escalation. The Trump administration's blockade threat and the Iranian parliamentary bill both signal a hardening of positions, making a diplomatic resolution more difficult.

Political Context

The escalation comes amid a broader US-Israel war on Iran that began on February 28. The conflict has already resulted in significant casualties and infrastructure damage. The Iranian parliament's move to formalize control over the strait reflects the influence of hardliners who oppose negotiations with the US and seek to assert Iranian sovereignty. Meanwhile, President Trump's blockade threat aligns with his administration's maximum pressure campaign against Iran.

What Officials and Groups Are Saying

Ebrahim Azizi, head of Iran's national security commission, wrote on social media that the parliamentary plan is the first step and that subsequent measures are forthcoming. The Hill reported that President Trump stated the US would reimpose the naval blockade and begin charging tolls immediately. No other officials have commented publicly on the military exchange.
