Iran on May 3 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. The U.S. Navy said in a statement that the Panama-flagged oil tanker Niovi was seized by Iran’s Islamic Revolutionary Guards Corps Navy (IRGCN) while passing through the Strait of Hormuz. Tehran's prosecutor said 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.
