Yes, landmines were a major weapon used by the Marxist black Liberation movements. Virtually all the landmines which are still out there today killing and maiming people (mostly black people) were planted by those who came to "liberate" them.

What is also never mentioned is that this effective, and yet hideous weapon was used most indiscriminantly against the whites in Rhodesia (now Zimbabwe). The "Liberators" (like Mugabe and Nkomo), sent their people to plant landmines on every road where it was possible. You can only plant them on non-tarred roads - and there are many such roads in the rural and farming areas of Zimbabwe. Landmines were planted everywhere. A farmer and his family might drive to town in the family car only to hit a boosted anti-tank landmine. What is a boosted landmine? It is one which has various other explosives packed around it to give it that extra punch. Well, if you hit a boosted anti-tank landmine with your family car there is pretty much nothing left of you or your car afterwards.
