Yemen's Houthi rebels have resumed their attacks on Red Sea shipping, saying they aim to force Israel to cease fire in Gaza -- a move that threatens a truce with Washington and rattles maritime trade.

Houthi rebels in Yemen have launched a violent new wave of attacks on ships in the Red Sea, sinking two vessels and killing crew members.

Video released by the Houthi media center shows the bulk carrier ‘Magic Seas’ being attacked and later sinking in the Iran-backed rebel group’s first attack this year on a commercial shipping vessel in the Red Sea.
