I looked it up. If the information is correct it means that there were 4200 dead (55% unidentified) from undetermined time which included the intensive guerilla and anit-guerilla warfare and earlier time, intensive NATO bombing, large movement of population during which normal funerals can be impossible (a significant number of people die in every large population for natural reasons while disease rate increases in time of chaos).
So what conclusion can you draw? 4200 (or less if you discount negative or missing identification) dead during such civil war combined with foreign intervention looks rather low to me.
