Iran seized a second oil tanker in a week in Gulf waters, and the U.S. State Department called for its release, in the latest escalation in a series of seizures or attacks on commercial vessels in Gulf waters since 2019.

The Bahrain-based Fifth Fleet of the U.S. Navy said the Panama-flagged oil tanker Niovi was seized by Iran’s Islamic Revolutionary Guard Corps Navy (IRGCN) at 6:20 a.m. (0220 GMT) while passing through the Strait of Hormuz.

In Iran’s first response, Tehran’s prosecutor announced the oil tanker was seized on a judicial order following a complaint by a plaintiff, the judiciary’s Mizan news agency said. No further details were provided.

The incident comes after Iran on Thursday seized a Marshall Islands-flagged oil tanker in the Gulf of Oman called the Advantage Sweet. That tanker is being held by Iranian authorities in Bandar Abbas, the Marshall Islands flag registry said on Tuesday.

Maritime security firm Ambrey has said it believed the Advantage Sweet’s seizure was in response to a recent seizure via a court order by the United States of an oil cargo aboard the Marshall Islands tanker Suez Rajan.

The Niovi oil tanker seized on Wednesday had been travelling from Dubai toward the UAE’s Fujairah port when it was forced by IRGCN boats to change course towards Iranian territorial waters, the Navy said.

The Niovi last reported its position at 0231 GMT on Wednesday off the coast of Oman in the Strait of Hormuz with Fujairah as its destination, Refinitiv ship tracking data showed.

According to the International Maritime Organization shipping database,, the Niovi’s owner is Grand Financing Co, and the ship is managed by Greece-based Smart Tankers, which did not immediately respond to a request for comment.
