By Renee Maltezou and Jonathan Saul ATHENS (Reuters) -Rescuers pulled six crew members alive from the Red Sea after Houthi militants attacked and sank a second ship this week, while the fate of another 15 was unknown after the Iran-aligned group said they held some of the seafarers.

The Houthis released dramatic footage of the sinking of the Liberian-flagged, Greek-owned Eternity C, which the rebels targeted with gunfire and explosive drones for hours, killing at least three crew members.
