This video, that first appeared on Telegram, clearly shows the missile that hit the hospital. The missile exhibits several characteristics, including the presence of what appears to be a jet engine at its rear as well as two short wings near the middle of the missile.
When placed side by side with 3D models of both the Kh-101 and the AIM-120, the missile clearly shares more characteristics with the Kh-101, a cruise missile used exclusively by the Russian armed forces.
