Iran's Revolutionary Guard on Thursday warned ships against sailing through the Strait of Hormuz without permission, saying vessels that do not comply "will be subject to action."
The Revolutionary Guard said in a statement that traveling through the strait without permission is "unacceptable and extremely dangerous."
The statement can be seen as a response to a message from Oman, which overnight established a temporary corridor on its side of the strait.
Iran and the United States agreed earlier this week to establish communication channels to keep the shipping lane open.
