Yemen's Houthi rebels on Friday released a video showing fires and explosions on a vessel in the Red Sea.<br /><br />It's thought that the vessel is the Sounion, a Greek-flagged oil tanker which had been attacked by the rebels earlier this week.<br /><br />It wasn't immediately clear what had happened to the oil tanker Sounion, which was abandoned by its crew on Thursday and reportedly anchored in place.<br /><br />Authorities now say the vessel appears to be adrift in the Red Sea. The group claimed the video was filmed on 22 August.
