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.

Israel's military launched airstrikes early Monday targeting ports and facilities held by Yemen's Houthi rebels, with the rebels responding with missile fire targeting Israel.
