3 prisoners get beheaded by the use of a Samurai sword. (the act is not shown, but there is blood on the sword.) After they get beheaded the exicutioner kicks their bodys over a ledge. (later breifly shown with minimal blood)
Several prisioners run into a barb wire fence that is electrified. When they hit, some sparks and fire are very briefly shown. Very fake and mild to todays standards. One man commits sucide by running into the fence.
People get hit and slapped by guards and other people. (no blood, but some bruses)
There is also a scene to where they take a dog and (to show to the prisoners) throw him agianst the electrified barb wire, killing him.
