DUBAI, United Arab Emirates (AP) — In just days, Yemen’s Houthi rebels have begun a new, more violent campaign of attacks targeting ships in the Red Sea, sinking two of them and killing some of their crew.

Houthi rebels in Yemen attempted to strike Israel’s Ben Gurion airport after sinking two vessels in the Red Sea this week, as the group ramps up its military pressure in support of Palestinians under Israeli fire in its bid to bring the war in Gaza to an end.

Rescuers pulled three more crew members and a security guard alive from the Red Sea on Thursday, maritime security sources said, a day after Houthi militants sank the Greek ship Eternity C and said they were holding some of the crew still missing.
