Iran’s parliament is reviewing a plan to ban ships linked to the U.S., Israel and other “hostile countries” from transiting the Strait of Hormuz until Tehran is compensated for war damage, according to Iranian state media.

The plan would impose fees of up to 7% of cargo value on commercial vessels that pass through the strait. It would also fine ships 20% of cargo if they violate Iran’s conditions.

Iran on Wednesday said it was finalizing an agreement on shipping routes with Oman, a U.S. ally that sits on the other side of the Strait of Hormuz. Iranian state media quoted the Foreign Ministry as saying that ships would enter through the strait’s northern corridor near the Iranian coast and exit through the southern corridor near the Omani coast.
