North builds nuke site test tunnels


North Korea has built two tunnel entrances at its nuclear test site in a sign that it plans to carry out more of its internationally condemned detonations, a U.S. think tank said Wednesday.

Satellite images taken on Sept. 27 shows progress in excavation work and the presence of two new entrances to tunnels at the Punggye-ri site, Johns Hopkins University’s U.S.-Korea Institute said. The research group said it had no reason to suspect an imminent test but that the work showed clear intentions to advance North Korea’s nuclear program.
