Park In Young—the name's spelling may be subject to changes depending on the translation and transcriptions—was the chief of North Korea’s Bureau 131, a division of the ruling party’s Central Committee charged with the supervision of military facilities such as the Punggye-ri underground nuclear test facility and the Sohae Satellite Launching Station.
The motive for the alleged exceution remains unclear. Asahi’s report mentions two potential reasons. One could be a delay in the execution of North Korea’s sixth and most powerful nuclear test to date, which happened on September 3 but was originally planned for the spring and was postponed due to delays in a tunnel construction.
Another reason may be that Park was held responsible for the collapse of a tunnel that, according to the Asahi TV channel sources, occurred in October and caused the death of around 200 people—a report North Korea vehemently denied.
The Asahi Shimbun also previously reported that North Korean soldiers and their families were treated in a military hospital for radiation exposure following the September hydrogen bomb test at the facility.
The hydrogen bomb test provoked a 6.3 earthquake which, according to reports mentioned in South Korean newspaper Chosun Ilbo, destroyed building facilities in a nearby village, including a school with more than 100 children in it as the regime gave no warning of the test.
Geologists have warned that a series of small-scale earthquakes recorded in the area following the September test indicate the facility may have become too unstable to conduct a new test without risking a massive collapse and radioactive leaks.
South Korean intelligence officers told lawmakers at a closed-door briefing in November a new nuclear test is unlikely, but it could nonetheless occur should Kim desire it, as one of the tunnels at the site seems ready for use.
News of Park’s alleged execution follow reports of punishment of North Korea’s second most powerful official after leader Kim Jong Un. General Hwang Pyong So of the General Political Bureau has vanished from public view, missing significant party meetings and celebrations, sparking speculation that he had been executed.
At the November briefing, South Korea’s intelligence agency said Hwang and his deputy were punished for “impure” attitudes. A lawmaker speaking to the press after the briefing said he could not comment on the details of the punishment because it was confidential information.
Last week South Korean publication Korea JoongAng Daily quoted an unidentified source saying that Hwang was purged from the party for taking bribes and his deputy was sent to a prison camp.
