Strait of Hormuz closure: Iran seals waterway, fires on tankers amid U.S. standoff

Strait of Hormuz closure escalates regional tensions

The Strait of Hormuz closure announced by Tehran on Saturday marks the latest flashpoint in a deteriorating U.S.-Iran standoff. Iranian officials warned they would seal the waterway if Washington persisted with what they described as a “blockade” of commercial traffic.

Fars News Agency, a semi‑official outlet, quoted a senior military commander: “As long as the United States refuses full freedom of navigation, the Strait will remain tightly controlled.” The statement came after ↓ 23 vessels reportedly obeyed U.S. orders to reverse course earlier this week.

“We will not tolerate banditry and maritime piracy,” the commander added, as reported by Reuters.

U.S. Central Command confirmed the reversals but declined to specify how many occurred after the official seal. Meanwhile, both a U.S. defense source and the U.K. Maritime Trade Operation said Iranian forces opened fire on tankers. At least three attacks were logged on Saturday, with two confirmed by the UKMTO. One Indian‑flagged tanker, laden with 2 million barrels of Iraqi crude, sustained damage but no injuries.

Audio logs released by maritime monitors show a vessel receiving clearance to enter the strait before gunfire erupted, prompting the pilot to order an immediate turn‑back.

The timing is stark: President Trump has hinted at a near‑term nuclear‑deal breakthrough, claiming Iran consented to halt enrichment “forever.” Negotiators were slated to reconvene this weekend, yet the closure throws a wrench into diplomatic calculations.

Analysts warn that the disruption could ripple through global oil markets, tightening supply routes that already carry ↑ 20 million barrels daily through the chokepoint.
