Landmines in form of Stones
Very dangerous because it is camouflaged and is placed in unexpected places and may explode as soon as you approach it
Landmines disguised as stones are detonated remotely, they can also be victim-activated by a photoelectric light control photocell like that used in electronic doors which open automatically when the person approaches them and closes automatically after entering. This type of landmine has been placed on the streets, on the sides of roads, sidewalks and public places such as parks and gardens, so be careful of stones that seem "out of place".
