Which phrase describes the author's perspective in Zlata's Diary best? unbiased observer persecuted victim firsthand observer wartime journalist

Zlata was present in Sarajevo during the War which she described in her diary, but she was not a journalist, in the sense that she was not educated in journalism and was not sent to Sarajevo to report on the war.

I think that the best answer is that she was a "firsthand observer" since she personally observed the events, but since she wasn't directly hurt herself, s he was not directly a victim.
