casing

Two Irish scientists have created a groundbreaking method for recovering fingerprints from fired bullet casings -- something long believed to be impossible.

Engineers had to design a well casing that could handle the subterranean inferno.

Protesters at the scene showed AFP journalists bullet casings they said they collected after security forces fired shots near the gendarmerie.

But a metal casing on well SS-25 had corroded, and gas began blowing out at very high volumes.

The military released what it said was drone footage from inside the tunnel, which showed several rooms, a bathroom, rocket casings and a lathe.
