Summary

Iran's Supreme National Security Council is planning to announce an "exclusion zone" outside the Strait of Hormuz, which will extend into the Persian Gulf. The new zone will be aimed at vessels attempting to transit the waterway and entering this area will result in being placed on Iran's sanctions list. According to Mohsen Rezaei, Iran's security chief, the zone should be announced within days or weeks. Over 20 US warships are currently supporting a blockade of Iranian ports, which has redirected 92 commercial ships and disabled three vessels as of Sunday.
