Many human rights groups criticised civilian casualties resulting from military actions of NATO forces in Operation Allied Force. Both Serbs and Albanians were killed in 90 Human Rights Watch-confirmed incidents in which civilians died as a result of NATO bombing. It reported that as few as 489 and as many as 528 Yugoslav civilians were killed in the NATO airstrikes. "There is always a cost to defeat an evil," said NATO spokesman Jamie Shea, "It never comes free, unfortunately. But the cost of failure to defeat a great evil is far higher." He insisted NATO planes had bombed only "legitimate designated military targets," and if more civilians had died it was because NATO had been forced into military action. He then defended this notion by stating, "NATO does not attack civilian targets, we attack exclusively military targets and take every precaution to avoid inflicting harm on civilians."
