I note that you re-did essentially the same changes to this article, even after I posted the above gentle notice.  Again, this material does not belong in the Decapitation article:  it goes way beyond the subject of this particular article, and perhaps more importantly, you removed material that was directly relevant to decapitation (along with sources for the same) in order to insert your out-of-scope information in its place.  It is very important that you do not keep on doing this.  Please also be aware that any treatment of Balkans-related topics anywhere in Wikipedia is subject to the Arbitration Committee's discretionary sanctions; see WP:ARBMAC#Standard discretionary sanctions.  —
