An anti-personnel mine is a very dangerous thing that is hidden on the ground or other places where people can step on it by accident. When someone steps on an anti-personnel mine, it will explode and cause a lot of harm to the person. It can hurt their body really badly and even kill them.
Anti-personnel mines are used by some bad people to hurt other people. They are not nice and we should never touch them or try to play with them. If we see one, we should tell an adult or someone who is in charge so they can get rid of it safely. It's important to stay away from places where we think there might be anti-personnel mines because they can hurt us very badly.
