More Nuke Testing? North Korea

N.Korea 'Could Conduct Fresh Nuke Test in 2 Weeks'

North Korea has the capability to conduct a third nuclear test within two weeks, U.S. nuclear experts claimed Monday. "North Korea appears to have an underground tunnel ready for testing," write Siegfried Hecker, the director of the Center for International Security and Cooperation at Stanford University, and Frank Pabian, a senior nonproliferation analyst at the Los Alamos National Laboratory, a the Bulletin of the Atomic Scientists.

"Commercial satellite imagery shows a recently excavated 'south portal' for a tunnel in Punggye-ri, situated very close to the tunnels for the first two tests" in 2006 and 2009, they add.
