This is one of several reports I have seen of the interdiction a dhow carrying weapons believed to have been en route from Iran to Yemen.
There are a number of unanswered questions about this operation. We don’t know who did the initial intercept and boarding. We don’t really know where the vessel was going.
What we do know is that the cargo included a number of anti-tank weapons, most of which were dumped at sea. A USN destroyer, USS Forrest Sherman, arrived on scene after the initial intercept to assist in the investigation. The dhow and its crew were released after the arms were confiscated.
I strongly suspect Coast Guard personnel may have been involved in this operation, if not directly, at least to the extent that they were involved in the training of those that were directly involved. Hopefully we will learn more in the future.
