Iran closes Strait of Hormuz once again, fires on tankers

Iran said on Saturday that the Strait of Hormuz is again closed to traffic following threats of such action if the U.S. continued its https://www.axios.com/2026/04/13/the-logic-behind-the-us-blockade" target="_blank">blockade of the shipping channel.

Why it matters: The closure could be a setback to efforts toward a new round of negotiations on a deal to end the war and will add pressure to an already tense situation between https://www.axios.com/world/iran" target="_blank">Iran and the U.S.

The latest: Fars, Iran's semi-official state news agency, first reported the closure, citing the ongoing blockade and quoting an Iranian official as saying that the U.S. "continue to engage in banditry and maritime piracy."

• "As long as the United States does not agree to the complete freedom of navigation for vessels .... the situation in the Strait of Hormuz will remain tightly controlled and in its previous state," the military official said, according to Fars.
• U.S. Central Command said 23 ships complied with U.S. instructions to turn around since the blockade began earlier this week.

  It was unclear how many of those ships received instructions after the Strait was closed.

Adding more strain are reports from a U.S. defense official and the U.K. Maritime Trade Operation (UKMTO) that Iran has https://apnews.com/article/us-iran-war-israel-hormuz-18-april-2026-ab475cb979825b956a10d60103026b37" target="_blank">fired on tankers in the Strait.

• A U.S. official told Axios that at least three attacks on commercial ships have occurred so far on Saturday, while the UKMTO reported two attacks.

  At least one ship was hit and caused some damage, but there were no reports of injuries.

Between the lines: The new developments come just hours after President https://www.axios.com/politics-policy/donald-trump" target="_blank">Trump said he https://www.axios.com/2026/04/17/trump-iran-deal-interview-pakistan-talks" target="_blank">expected a deal with Iran "in a day or two."

• Trump repeatedly said Friday that Iran had agreed to several stipulations the U.S. has been pushing for in talks, including that Iran agreed to https://www.cbsnews.com/news/trump-says-iranians-have-agreed-to-everything-including-removal-of-enriched-uranium/" target="_blank">stop enriching uranium "forever."
• Negotiators for the U.S. and Iran are expected to meet this weekend to continue peace talks.

  It's unclear if that will go ahead.

• The White House did not respond to a request for comment.
