Yemen's Houthi rebels on Monday claimed an attack on Israel and said Israel-affiliated vessels would again be a target in the Red Sea.

The statement from Brig. Gen. Yahya Saree was broadcast on the Houthis' al-Masirah satellite news channel.

It's another new escalation as the nominal ceasefire in the Iran war is being challenged by crossfire between Israel and Iran.

The Houthi threat to target vessels again puts the Red Sea, the Gulf of Aden and the narrow Bab el-Mandeb Strait connected them in danger.

The Houthis during the Israel-Hamas war in the Gaza Strip killed at least nine mariners and sunk four ships across over 100 attacks. Those assaults upended shipping in the Red Sea, through which about $1 trillion of goods passed each year before the war.

The attacks greatly disrupted transit through Egypt's Suez Canal, which links the Red Sea to the Mediterranean. The canal remains one of the top sources of hard currency for Egypt, providing it $10 billion in 2023 as its wider economy struggled.

The Houthis' attacks during that period often targeted vessels with tangential or no ties at all to Israel.
