What did it hit? Was it only a Russian claim?
In the videos that I have seen, there are no explosions.
My guess is that the missile was launched with inert warheads. No time to manufacture HE warheads to exact specifications.
The missile was not launched at Kyiv for fear that Patriots would shoot it down.
All in all, the launch was a testament to ruzzian stupidity.
It clearly caught the attention of the FRchickenlittles.
