[1] As a result of his experiences Dulmers was able to testify against Bosnian Serb paramilitary group leader Nikola Jorgic, who was sentenced to life in prison for genocide in 1997.
Reviewing Zwart ("Black"), Dulmers' autobiographical novel based on his experiences in former Yugoslavia, Voeten called it "an impressive and, as far as I know, unique book for Dutch literature: a philosophical confessional novel with homo-erotic subtext, Bildungsroman and ruthless war reporting at the same time".
[3] In the late 1990s Dulmers worked, still as a freelance writer, for a number of Dutch publications including again Vrij Nederland, which fired him in 1999 after he was charged with plagiarism: one paragraph (five sentences[4]) in a long article on safe sex was copied from the Internet.
[8][9] Dulmers commented afterward that in war journalism it is frequently impossible to report on both sides: "If they [the rebels] find out that I visited at the presidential office, then I'm finished".
When he posted a photo of the aftermath of a Russian rocket attack on a fuel warehouse in Odessa on Twitter, he was arrested and accused of revealing state secrets.
