Bosnian Muslims fought in the Nazi Hanzar division (made up of exclusively Muslims) against the Jews in the Balkans. This division was supervised by Amin al-Husayni, the grand mufti of Palestine. He too collaborated with the Nazis.
Not sure if you have seen this site TellTheChildrenTheTruth.com, but it ties it all together, and Amin al Husseini was the father of it all -- Islamic Nazism right up to Osama bin Laden The flag in the opening sequence with the scimitar & swastika was the Bosnian Handzar Division's flag & the troops Husseini is inspecting in the photos are Handzar.
Handzar fought against the Serbs primarily, and helped round up Jewish civilians to hand over to the Germans.
Alija Izetbegovic, first president of an independent Bosnia was also a Handzar Youth recruiter during WWII.
