An Iranian oil tanker pursued by the U.S. has turned off its tracking beacon for over 13 hours, leading to renewed speculation that it's heading to Syria.
The Adrian Darya 1, formerly known as the Grace 1, turned its Automatic Identification System off on Monday night.
Previously, the ship-tracking website MarineTraffic.com showed the Adrian Darya off
Lebanon on a course toward Tartous, Syria.
