On the 4th of July, 2019, the Iranian tanker Grace One was detained by UK forces in Gibraltar on suspicion of EU sanction violations and on the 19th of July a British flag tanker, the Stena Impero was detained by Iran's Islamic revolutionary guard Corps. Track forward to August 2020, and we find Iranian forces once again, boarding another vessel this time a Liberian flag tanker, the MV Wila.  Are these events connected and should shipowners be concerned with the apparent escalation of hostilities in the Persian Gulf. We'll aim to answer these questions with Cormac McGarry senior analyst at Control Risks and Jonathan Wood lead analyst for North America and deputy global research director for Control risks.
