A previous incident occurred six days ago when the Islamic Republic of Iran Navy seized Marshall Islands-flagged suezmax tanker Advantage Sweet. Greek authorities had issued a warning, that Greek shipping was at an increased risk from Iran after the detention of the Suez Rajan.

“Due to recent Iranian threats of possible retaliation against Greek shipping, we strongly recommend the navigation in the above area as well as in the Straits of Hormuz and the Gulf of Oman to be carried out, if possible, outside the waters under Iran’s jurisdiction, and under increased caution when sailing near the above areas,”

Shipping Ministry of Greece (April 20th)

Maritime security company Ambrey said following the initial warning by Greece’s shipping ministry, it has observed the exodus of an unusually high number of Greek-flagged vessels from the Gulf region.

“the risk to merchant shipping was not limited to the flag-state but to the affiliations with Greece and the U.S.”

Moments before the seizure, Advantage Sweet issued a distress call. When seized by the Iranian forces, the vessel transited international waters in the Gulf of Oman in retaliation for a Greek-managed tanker Suez Rajan being taken by US authorities, particularly Washington for carrying Iranian oil.

Iranian media claimed a regular Iranian Navy corvette seized the tanker and directed it to Iranian coastal waters, claiming the tanker had collided with an unidentified Iranian boat.

“Iran’s actions are contrary to international law and disruptive to regional security and stability. Over the past two years, Iran has harassed, attacked or interfered with the navigational rights of 15 internationally flagged merchant vessels.”

“Iran’s continued harassment of vessels and interference with navigational rights in regional waters are unwarranted, irresponsible and a present threat to maritime security and the global economy,”
