Picture of a small brown "butterfly" or "petal" mine next to a ruler to show size

The top-view of an exploded PFM-1S antipersonnel mine, also called a “butterfly” or “petal” mine, found by Human Rights Watch in the Izium area in September 2022. The mine comes in multiple colors, including green and brown. The mine is filled with 37 grams of liquid explosive and is designed to detonate when enough cumulative pressure is applied to the body of the mine. PFM-1S mines are equipped with a self-destruct fuze that is designed to self-detonate after up to 40 hours, but the mechanism often fails, making the mine dangerous for years to come.
