DUBAI, United Arab Emirates (AP) — Satellite images appear to show the once-detained Iranian oil tanker Adrian Darya-1 near the Syrian port of Tartus, despite U.S. efforts to seize the vessel.

Images obtained by The Associated Press early Saturday from Maxar Technologies showed the vessel there.

Iranian officials haven't acknowledged the ship went to Syria. The ship turned off its Automatic Identification System late Monday.

The new images matched a black-and-white image earlier tweeted by John Bolton, the U.S. national security adviser.

Bolton had tweeted: "Anyone who said the Adrian Darya-1 wasn't headed to #Syria is in denial."

Authorities in Gibraltar had seized the ship in July over concerns it would break European Union sanctions on Syria. They later released it after they say they received a promise from Iran that the vessel wouldn't go there.
