North Korea has covered the entrances to two tunnels at its remote nuclear test site, fanning speculation that it may be about to detonate another nuclear bomb.
Camouflaged covers over tunnels at nuclear test sites are considered clear signs of an impending test.
The South Korean military believes the North could conduct another nuclear test around Oct. 10, the founding day of the North Korean Workers Party.
North Korea has dug three tunnels at the site in Punggye-ri, North Hamgyong Province. The first was used for the first nuclear test in 2006, while the second to fifth nuclear tests took place in tunnel No. 2.
A government source here said, "There are suspicions that North Korea may conduct a sixth nuclear test at tunnel No. 3, which has never been used."
