Former two-star general and now a tunnel hunter, General Hahn Sungchu, believes that North Korea is still digging tunnels into South Korea.

Hahn stated that residents were complaining of underground vibrations even though there is no subway running under them. This prompted the former general and his team to search for tunnels and they claim that they discovered three tunnels 13-16 feet wide and 39 feet deep.

The team then drilled two holes in order to lower a camera but before being able to do so two underground explosions were set off and the holes were blocked.

In Korea’s history, four tunnels in total have been found in South Korea but none have been discovered since 1990. The South Korean Defense Ministry believes there to be about 20 tunnels and still looks for them but it’s a token effort since the South is less concerned about a tunnel invasion and more about a nuclear attack from the North.

Kim Minseok, Defense Ministry Spokesperson, has stated that there is a possibility of tunnels but that none would ever be able to reach Seoul. She was quoted, “To dig tunnels tens of kilometers, it must be angled properly…South Korea and the U.S. have always taken aerial photographs, and we found no evidence of this.”

On the contrary, a former intelligence official from North Korea, has said that the notions are not as far-fetched and that “…the tunnels are not directly connected to the streets of Seoul because of the risk of being detected. The tunnels are connected to the sewers linked to the relevant organizations.” These would be organizations such as the U.S. Embassy, The Blue House, and other governmental buildings.
