American journalist, Danny Fenster, was sentenced to 11 years in prison by a Myanmar court on Friday after being found guilty of various offenses, including incitement for allegedly circulating false or provocative material.

The managing editor of the online journal, Frontier Myanmar, was also found guilty of breaking visa regulations and being involved with criminal organizations.

Since May, Fenster has been held in custody by the Myanmar military. He still faces two further counts in a different court for allegedly breaking the country’s counterterrorism legislation, sedition laws, and treason.

Despite the evidence of over a dozen prosecution witnesses, it was never apparent exactly what Fenster was accused of. Much of the prosecution’s evidence seemed to depend on his employment at Myanmar Now, one of the media sites that had been ordered closed earlier this year. However, Fenster departed Myanmar Now in July of last year and joined Frontier Myanmar the following month.

Frontier Myanmar’s Editor-in-Chief Thomas Kean said that everyone at the publication is “disappointed and frustrated” at the decision. He added that they are calling for Fenster’s immediate release so he can go home to his family.

On May 24, Fenster was intercepted by military police at Yangon International Airport as he was preparing to board an aircraft to meet his family in Detroit. Fenster is the only foreign journalist to have ever been convicted of a felony since the military seized power and overthrew Aung San Suu Kyi’s civilian government.

 The military-installed administration has repressed press freedom, closing down nearly all critical outlets and detaining approximately 100 journalists, about 30 of whom are still in custody. Some of the shuttered publications have continued to operate without a license, publishing online while their employees avoid imprisonment.
