Russia never bomb themselves with a nuclear weapon. But in 1908, a very big meteor landed in Siberia. Known as the Tunguska Event. The after effects were similar to a nuclear blast. Land and forests were scorched and devastated. No cities were destroyed. No one knew about it until a few years later.
I've never heard of them nuking (if you mean nuclear bombs) themselves... If they are (and I don't know it) they might have had a fight between different parts of the country.. But honestly, I have no clue... Sorry :-/
