According to the sources, police discovered 23 Christians in Kuwal-dong, Pyungsung County, in Pyongan Province, who met as an underground church. After their arrest, they were interrogated at length. Eventually, the group's "ringleaders" were sentenced to death and executed. The others were sent to Kwan-li-so (Penal labour colony) No 15 in Yodŏk.
"As the authorities fear the spread of religion, many area residents are rounded up and interrogated for days," the sources said. However, "they cannot help it because the situation is so desperate that people are going back to religion. Such sentences are meant to scare people."
These North Koreans discovered underground Christianity when some of them travelled to mainland China for work.
