WASHINGTON: The State Department issued a sharp warning to Americans Tuesday against travel to North Korea after the arrest of a fourth US citizen, cautioning against the "serious risk" of lengthy detention and "unduly harsh sentences."
Kim Hak-Song was detained over the weekend for "hostile acts," the official KCNA news agency said, adding he had worked for the Pyongyang University of Science and Technology (PUST).
The arrest put the number of Americans held in North Korea at four, as Washington and Pyongyang remain at loggerheads over the North's nuclear and missile ambitions.
While a travel warning already was in effect for US nationals, the State Department offered a more detailed statement about the pitfalls of heading to North Korea .
"US citizens in the DPRK are at serious risk of arrest and long-term detention under North Korea 's system of law enforcement," the department said. (APP)
