Crew members aboard a Liberian-flagged ship set ablaze by a series of attacks in the Red Sea abandoned the vessel Sunday night as it took on water, marking the first serious assault in the vital corridor for trade after a monthslong campaign by Yemen's Houthi rebels there. Suspicion for the attack on the Greek-owned bulk carrier Magic Seas immediately fell on the Houthis, particularly as a security firm said it appeared bomb-carrying drone boats hit the ship after it was targeted by small arms and rocket-propelled grenades. The rebels' media reported on the attack but did not claim it, the AP reports. It can be hours or even days before they acknowledge an assault.
