The Iranian Revolutionary Guard Corps (IRGC) has released a map portraying alternate shipping routes in the Strait of Hormuz for ships to avoid naval mines, according to local media reports.

The circle on the map below is labelled an “area of danger”. The IRGC Navy says ships must coordinate with them to avoid naval mines.

Tankers that used to pass close to Oman, which is in the south of the Strait, are now being told to take a more northerly route, closer to the Iranian coast.
