Israeli defence sources have confirmed targeted strikes on two key ports in Yemen: Hudaydah and Port of Salif.
Dozens of precision munitions were reportedly used in the operation.
The strikes come amid heightened regional tensions, with Israel intensifying efforts to disrupt Iran-backed Houthi operations in the Red Sea.
Hudaydah and Salif are critical logistical hubs used by the Houthis for arms shipments and maritime attacks.
The Israeli military has not formally commented, but the action is believed to be part of broader pre-emptive measures against hostile activity in the region.
