A battle between rival drug cartels in a northern Mexico prison left 44 dead early Monday morning. The violence began around 2 a.m., with inmates attacking each other with knives and stones. A fire broke out shortly after the riot began, and there were reports of gunfire, though prison officials say no firearms were used. Some prisoners may have escaped. Corrupt guards may have helped facilitate the fight, and all prison officials have been held for questioning.
