Iranian media said the Islamic Revolutionary Guard Corps (IRGC) was bringing two ships to Iran after seizing them in the Strait of Hormuz, according to The Associated Press.
The Islamic Revolutionary Guard Corps Navy (IRGCN) command claimed in an X post that the two vessels, the MSC-Francesca and Epaminodes, "had endangered maritime security by operating without the necessary permits and tampering with navigation systems."
It said the vessels "were seized by the IRGC Navy and escorted to Iran's coast," according to a translation.
"Disruption of order and safety in the Strait of Hormuz is our red line," the command wrote.
It also claimed the MSC-Francesca is "linked to the Zionist regime."
Iranian media also reported that the IRGC attacked a third ship, identified as the Euphoria, according to the AP.
The development comes after President Donald Trump announced Tuesday afternoon that the United States was extending a ceasefire.
"Based on the fact that the Government of Iran is seriously fractured, not unexpectedly so and, upon the request of Field Marshal Asim Munir, and Prime Minister Shehbaz Sharif, of Pakistan, we have been asked to hold our Attack on the Country of Iran until such time as their leaders and representatives can come up with a unified proposal," the president wrote on Truth Social..
"I have therefore directed our Military to continue the Blockade and, in all other respects, remain ready and able, and will therefore extend the Ceasefire until such time as their proposal is submitted, and discussions are concluded, one way or the other," he added.
