"NATO said "there may have been a weapons system failure which may have caused a number of civilian casualties." A military missile site was the intended target of the air raid, NATO said, but "one weapon" apparently went astray. "NATO regrets the loss of innocent civilian lives and takes great care in conducting strikes against a regime determined to use violence against its own citizens," said Canadian air force Lt. Gen. Charles Bouchard, commander of the Libya campaign. Investigators were still "determining the specifics of this event," Bouchard said."
