Iran announced on Sunday that it has closed the Strait of Hormuz, claiming a vessel was moving through an unauthorized route and was stopped after being attacked. The Islamic Revolutionary Guard Corps (IRGC) Navy stated that the ship had turned off its identification system, disrupting maritime security. The IRGC warned that the strait would remain closed until further notice and until U.S. interference in the region ends, adding that any aggression against Iran would be met with a strong response.

Senior U.S. officials said on Friday that Washington wants Iran to publicly commit to halting attacks on ships and to keep all maritime routes open without tolls. U.S. President Donald Trump confirmed that despite rising tensions, both sides agreed to continue talks and that a ceasefire had ended. Reuters reported that Iran, the United States, Qatar, and Pakistan had agreed in principle to hold discussions, with Oman facilitating contacts.

Oman’s foreign minister met Iran’s Abbas Araghchi in Muscat to discuss measures ensuring safe navigation. Oman’s state news agency said technical and political talks on the issue would continue. The conflict, which began after U.S. and Israeli airstrikes on Iran in February, has driven up global energy prices.
