CLARK, Philippines, Oct. 23 (Yonhap) -- Even if North Korea wants to conduct another nuclear test, it may be facing a big hurdle to preparations at its testing site amid signs of topographic damage from the previous experiment, an informed South Korean defense source said Monday.
"The possibility of North Korea's additional provocations remains open all the time," the source said in response to the weeks-long break in its belligerent acts, as the South's Defense Minister Song Young-moon visited the Philippines to participate in the ASEAN Defense Ministers' Meeting (ADMM)-Plus session.
