I have also seen one or more comments on another post about this situation (I think on Hexbear) saying it might have been one of the Iron Dome missiles. That the supposed failed rocket from Hamas failed to launch correctly, but was maybe high enough to still have caused a lock-on by the ID. Though I don’t know enough about how the dome works to really say how likely it would happen. As it could be an opportunistic moment for Israel to launch a few non-ID attack missiles. While the media would be more likely to be streaming the air-explosions from the intercept missiles.
