NEW: Yemen's National Army — the anti-Houthi legitimate government forces — unveiled its "Eiban" (Ayban) one-way attack drone, along with a second system called "Naqm." The airframes look nearly identical to the US LUCAS drone, which itself was reverse-engineered from the Iranian Shahed-136 that Houthis have been using against Saudi Arabia and shipping. Whether the drones were directly supplied by the US, assembled from kits, or locally cloned is still unclear. It gives the anti-Houthi side a low-cost saturation weapon for the first time.
