BANGKOK — A court in military-ruled Myanmar on Friday sentenced U.S. journalist Danny Fenster to 11 years in prison with hard labor, the maximum penalty under three charges, despite calls by the United States and rights groups for his release.

It was the harshest punishment yet among the seven journalists known to have been convicted since the military ousted the elected government of Nobel laureate Aung San Suu Kyi in February.

Fenster, the managing editor of the online magazine Frontier Myanmar, still faces additional terrorism and treason charges under which he could receive up to life in prison.

The court found him guilty on Friday of spreading false or inflammatory information, contacting illegal organizations and violating visa regulations, lawyer Than Zaw Aung said.

Fenster wept after hearing the sentence and has not yet decided whether to appeal, the lawyer said.

The harsh penalty is the ruling military’s latest rebuff of calls from around the world for a peaceful end to Myanmar’s political crisis. The government is refusing to cooperate with an envoy appointed by Southeast Asian governments to mediate a solution, and has not bowed to sanctions imposed by the United States and several other Western countries.

U.S. State Department spokesperson Ned Price in a statement called Fenster’s sentencing “an unjust conviction of an innocent person.”

Price added: “The United States condemns this decision. We are closely monitoring Danny’s situation and will continue to work for his immediate release. We will do so until Danny returns home safely to his family.”

U.N. human rights chief Michelle Bachelet said Fenster’s conviction and harsh sentence “is emblematic of the wider plight of journalists in Myanmar who have been facing constant repression since the Feb. 1 military coup.”

According to Bachelet, at least 126 journalists, media officials or publishers have been detained by the military since the military seized power and 47 remain in detention, including 20 charged with crimes.

Nine media outlets have had their licenses revoked, 20 others have had to suspend operations, and dozens of journalists remain in hiding due to outstanding arrest warrants, she said. (AP)
