Israel has carried out its first strikes against Houthi targets in Yemen since the Israel-Iran ceasefire, attacking ports and a power plant around midnight local time Sunday night into Monday morning.

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

The Houthis attacked the Liberian-flagged, Greek-owned bulk carrier Magic Seas with drones, missiles, rocket-propelled grenades and small arms fire on Sunday, forcing its crew of 22 to abandon the vessel.
