There are and were no “blue helmet” peacekeepers in Kosovo. All NATO and under NATO (not UN) command. There was also a UN Mission (UNMIK), but it was strictly civilian.
Don’t ruin it for him, let him think that.
-—”The report, dating from 2003, is an incomplete compilation of investigations carried out by UNMIK”
Read the last page of the PDF and see what this is, it’s NOT an investigation, it’s what a journalist “the credibility of whom is untested” heard from some people. And UNMIK and EULEX went to house twice and found zilch, or they would filed charges. Dick Marty who said it happened but I can’t tell you details said that these witnesses were lying, since it supposedly happen in a different town, near Tirana. So many versions of the same lie. You cannot extract organs like that, even if you wanted to, any doctor will tell you.
