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.

Yemen's Houthi rebels have once again targeted maritime traffic in the Red Sea, sinking the Liberian-flagged cargo vessel Eternity C. The attack resulted in at least three crew fatalities, with only six out of the 25 crew members rescued so far.
