Iranian Deputy Foreign Minister Kazem Gharibabadi said on Friday that safe navigation through the Strait of Hormuz could not be guaranteed through "ambiguous arrangements," parallel shipping routes or decisions made without regard to Iran as a littoral state.

"Safe passage in the Strait of Hormuz cannot be guaranteed through ambiguous arrangements, parallel routes or decision-making outside Iran's considerations as a coastal state," Gharibabadi wrote on X.

He said any "credible framework" for navigation must be based on coordination with Iran and on Article Five of the Islamabad memorandum of understanding.

"Otherwise, the designated parallel route will be suspended," he said.
