Athens has received no request from the Iranian tanker Adrian Darya to dock in Greece, merchant marine minister Ioannis Plakiotakis said Tuesday after a maritime tracker gave the ship's "reported destination" as the Greek port of Kalamata.
"There is officially no request concerning the arrival of the Iranian tanker in a Greek port," Plakiotakis told Greek media.
"We are following its progress and are working with the Greek foreign minister," he said.
The website Marine Traffic placed the supertanker carrying 2.1 million barrels of oil some 100 kilometres (60 miles) northwest of the Algerian port of Oran.
The British Royal Marines seized the ship on July 4 off British territory Gibraltar on suspicion it was shipping oil to Syria in breach of EU sanctions.
