US immigration authorities have raided a massive Hyundai manufacturing site in Georgia, leading to the arrest of over 450 people allegedly in the country illegally.
The 3,000-acre site, which was built by the Korean automobile manufacturer to make electric vehicles, had been operational for a year.
The Department of Homeland Security told the BBC's US partner CBS News that agents executed a search warrant due to allegations of "unlawful employment practices and other serious federal crimes".
Korean nationals were among those detained, the South Korean foreign ministry said, calling it an "unjust infringement" of their rights.
"The economic activities of Korean investment companies and the rights and interests of Korean citizens must not be unfairly infringed upon during US law enforcement operations," the statement said.
