is this the one where Dostums forces, fired on prisoner containers?
May be you haven't really heard why JiM soldiers did what they did to Taliban prisoners.
remember 1997, when Taliban Entered Mazar-e Sharif and went house to house and killed about 8000 hazaras... After removal of Abdul Malik Pehalwan from junbish-e-milli and return of Rashid Dostum, Hazaras commanders from mazar joined a predominantly uzbek junbishi.
dashte laila massacre - if not mistaken were the prisoners of qala-e-jangi fort, and three of the commanders of the Junbish were hzaras, 2 of them veteran dostum's uzbek commanders one out them was son of General Abdullah karim.
In 97 taliban suffocated hazaras in container, payback was un-evitable. Although a despicable act, I think context is necessary to know what happened and why it happened.
