KIGALI, Rwanda — Carved into the side of a steep hill on the outskirts of Kigali is a tunnel where tin was once mined. It’s now cordoned off with a metal gate, a lock, and a red sign that reads: “Permanently closed.”
Behind that locked gate, there’s a winding, dark path chiseled into the depths of the hills. Lying midpath is a shriveled, lifeless bat sprawled on its back with a grimace.
At the path’s end is another locked red door with a sign that reads: “Beware of the Bat” — a warning that seems more fitting for a Halloween party.
