Iran’s Islamic Revolutionary Guard Corps (IRGC) has announced the closure of the Strait of Hormuz, accusing the United States of violating a ceasefire agreement. According to a statement reported by Al Jazeera, the IRGC said the closure would take effect from Saturday evening and remain in place until further notice. The group alleged that while several ships had crossed the strait the previous day, the U.S. failed to lift its naval blockade on Iranian vessels and ports, which it described as a breach of the ceasefire terms.

The IRGC warned all ships in the Persian Gulf and the Sea of Oman not to leave their anchorages, cautioning that any vessel approaching the Strait of Hormuz would be considered as cooperating with the enemy and could be targeted. It instructed ship operators to follow only official IRGC Navy communications and Channel 16 directives. The statement also dismissed the U.S. president’s remarks on the region as unreliable and unacceptable.

The closure raises immediate concerns for maritime traffic and regional stability, though no timeline for reopening was provided.
