Nasa discovers hidden Cold War-era 'secret city' beneath Greenland's ice sheet
A Nasa survey unearthed Camp Century, a hidden Cold War-era US military base beneath Greenland's ice. Built in the 1960s for Project Iceworm, the base was intended to house nuclear missiles aimed at the Soviet Union. Abandoned in 1967, its rediscovery raises concerns about thawing ice exposing hazardous materials.
