It is the first time Israel attacks Yemen from the sea, writes the newspaper The Times of Israel. Usually, the Israeli attacks against the Iran-backed Houthi movement in Yemen take place via air.
On Monday evening, Israel's military ordered an evacuation of the Houthi-controlled port cities of al-Hudayda, Ras Isa and Salif on the Red Sea.
Houthi extremists regularly fire projectiles at Israel, but the majority are shot down. Israel, on its part, has carried out several major air strikes against Yemen recently.
