 On the day of the surrender, two prisoners committed suicide with grenades and killed one of Dostum's commanders and some others in two separate incidents at the makeshift prison.Despite the deaths, the National Islamic Movement militia did not reinforce security at the prison.John Kerry's report for the United States Senate Committee on Foreign Relations later alleged it was a pre-planned "Trojan Horse" style operation, a gambit that would allow a die-hard force of foreign fighters to take over a strategically important fortified position at Qala-i-Jangi and capture a massive munitions stockpile.
