WATCH | US daycare workers charged after child 'fight club' video surfaces

Two daycare workers in St. Louis have been charged with endangering the welfare of children after a 2016 video of a "fight club" surfaced.

The children were 3 and 4 years old, St. Louis Circuit Attorney Kim Gardner's spokeswoman, Susan Ryan, told CNN. 

CNN reports the women directed at least six children to have fistfights.

A video shows at least six children fighting for more than 35 minutes, according to prosecutors.
