A new travel warning has been issued by the U.S. State Department regarding American citizens’ travel to North Korea.
Issued May 16, the warning “strongly urges U.S. citizens to avoid all travel to North Korea due to serious risk of arrest and long-term detention.”
The warning says 14 US citizens have been detained in the isolated country over the past decade.
“North Korea’s system of law enforcement,” continued the statement, “imposes unduly harsh sentences, including for actions that in the United States would not be considered crimes.”
The warning includes a 12-point list of actions for which North Korea has detained individuals in the past.
One is the “removing or tampering with political slogans and signs or pictures of political leaders.”
The travel warning, which replaces a warning previously issued on Nov. 20, 2015, comes after the conviction and imprisonment of two American citizens since the beginning of the year.
In March, North Korea’s highest court convicted Otto Warmbier, a University of Virginia undergraduate, of “subversion” after he confessed to stealing a propaganda banner.
The 21-year-old Ohioan was sentenced to 15 years in prison with hard labor.
On April 29, 62-year-old Kim Dong Chul was convicted of espionage and subversion. Kim was sentenced to 10 years in prison with hard labor.
Like Warmbier, Kim issued a confession to international media, in the presence of North Korean officials.
According to CNN, Kim claims to have been “tasked with taking photos of military secrets and ‘scandalous’ scenes” by “South Korean conservative elements.”
