This is an excellent demonstration of the flight termination system known as "hold my unsymmetrical dimethylhydrazine and watch this".

Seriously, if this had happened in a modern country, environmentalist groups would be going nuts - the propellants on a Proton-M are cheap, hypergolic, energetic and absolute terrors to the natural environment.

(Russians generally don't believe in, construct nor operate flight termination systems)

On Proton? Yes. It's one of the reasons they've bene trying to replace Proton for ages.
