Eighty South Koreans who were possible victims of fake jobs or scam centers were unaccounted for in Cambodia, South Korea's foreign ministry said Tuesday, after the torture death of a student there shocked the country.

Between January and August this year, 330 South Koreans were reported to have gone missing or been held against their will after entering Cambodia, a foreign ministry official said.

As of August, "the safety of about 80 people has yet to be verified", the official added.
