Images allegedly show construction at North Korea nuclear facility thought to be destroyed

Satellite images out of North Korea reportedly show construction at a nuclear testing facility.

"In the image, we see very early signs of activity at the new site, including construction of a new building, repair of another building and what is possibly some lumber and sawdust," he said. "North Korea uses a substantial amount of wood at the site both for buildings and shoring up tunnels. These changes occurred only in the past few days."
