Article revised for flow, and minor corrections
I have made a start on editing the article’s minor errors of grammar, syntax and flow. I hope this is acceptable to the other editors who have already done such a good job here. Although I have changed the order of some of the information (trying to lead from the general to the particular), I have not removed any so far as I am aware. I have added some details about the attack on the cornerstone ceremony. I have also revised the numbers of aggressors and victims in this attack, in line with those in the existing cited sources. I’m not sure where the article’s original figure of 4,000 Serbs came from. Have I overlooked a reference?  If so I apologize and ask that it be restored. Anyway this change may well be temporary if someone can find other equally (or more) reliable souce(s).

If the established editors here are unhappy with what I've done, please feel free to revert.

I think the article could use quite a few more cites.
