In response, Iran attacked multiple oil tankers and US vessels while warning ships in the Persian Gulf to avoid traversing illegal shipping lanes.

On the 6th (local time), Rezaei, Secretary of Iran's Supreme National Security Council, announced that the Strait of Hormuz region would be declared a "no-go zone" in the coming days, extending from the US Navy blockade line to certain waters within the Persian Gulf. Vessels entering this zone would be placed on a sanctions list.
