Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy has issued a statement warning vessels against transiting the Strait of Hormuz via any routes it has not authorised, saying they will face a “decisive response”, Al Jazeera reports.

“We warn all vessels that intend to transit the strait, the only safe route… is the corridor previously announced by Iran,” the statement, carried by Iran’s Fars news agency, says.

“The diversion of vessels to other routes is unsafe and will face a decisive response from the IRGC Navy.”
