The cold-storage units at the Hariri hospital have been fashioned into ad hoc laboratories to identify a relentless influx of dead bodies.

The unprecedented scales of DNA identification of corpses is born of a macabre need. Last week, after Iran and the U.S. agreed to a ceasefire, Israel pressed on in its Lebanese front with a ferocious blitz of airstrikes. The toll was staggering, leaving demolished buildings and infrastructure, along with the attendant skyrocketing casualties — the violence rending people into unrecognizable forms.

“The bodies arrive completely disfigured,” said Hisham Fawwaz, director of the hospitals and dispensaries department at the Lebanese Ministry of Health, which operates the hospital. “The remains are scattered and the features obliterated. We are often not dealing with whole bodies. We are dealing with human fragments that the force of the explosions has turned into medical puzzles.”
