Looks like a drone strike with low-yield weapons. Most likely the Saudis, using a Chinese drones. So expect the western MSM to blame China.
Wasn't the target the Saudi delegation visiting? The people behind it was probably Houthi rebels. Looks like ballistic missile. They were probably hoping to hit the Saudis so those were very inaccurate ballistic missiles. But the rebels owning any primitive ballistic missiles is a surprise in itself. Drones would have hit the plane or VIPs with pinpoint accuracy. These may be very old Soviet short range ballistic missiles that have been sold, owned, and resold for decades on the black markets.
