The U.S.–Iran maritime picture has just crossed an important threshold: **enforcement**.

Dryad Global’s latest **Maritime Intelligence Brief (Updated 21 April 2026)** tracks the seizure of the Iranian-flagged container ship **M/V Touska (IMO 9328900)** after it attempted to breach the ongoing U.S. naval blockade of Iranian ports. The vessel was disabled and boarded, and remains in U.S. custody, a clear signal that blockade posture is now being actively applied at sea.

This edition also brings together the wider risk picture: what this means for **commercial routing, compliance exposure, regional escalation dynamics**, and the latest global incident trends across key maritime theatres.

If you manage vessels, insurance exposure, or security posture in or near the Gulf, the detail matters.
