A ship off the coast of Yemen in the Red Sea has been attacked, private intelligence firms said Tuesday.

The attack on the vessel comes as threats have increased from Yemen's Houthi rebels on commercial shipping in the area over the Israel-Hamas war raging in the Gaza Strip. The Houthis did not immediately claim responsibility for the attack, though rebel military spokesperson Brig. Gen. Yahya Saree said an important announcement would be coming from them in the coming hours.
