Two Liberian-flagged ship attacks and a round of Israeli airstrikes early Monday targeting Houthi rebels raised fears of a renewed Houthi campaign against shipping.

D UBAI: A damaged cargo ship is under “continuous attack” in the Red Sea, a maritime monitor said today, after Yemen’s Houthi rebels ended a months-long lull in their harassment campaign of the vital but volatile waterway.

A Liberian-flagged cargo ship came under fire on Monday in the Red Sea, with two security guards on board reportedly hurt and two others missing in an assault that came after Yemen's Houthi rebels purportedly sunk another vessel in a similar attack.
