North Korean forced laborers in Russia who attempt to escape are tortured before they are repatriated.
A source who spoke to South Korean news service Daily NK on the condition of anonymity said North Koreans who try to flee work sites are persecuted in Russia at the hands of guards.
Some of the North Koreans endure bodily torture that includes the severing of the Achilles tendon, the source said.
The torture takes place in Russia before the laborers are forcibly returned to the North.
The human rights abuses take place in order "to make an example of North Koreans workers who are caught trying to escape," the source said.
Other punishment includes forcing the suspect to lie down while an excavator, used for heavy construction, runs over his legs.
"Ruthless human rights violations are being committed," the source added.
