A court in Myanmar has sentenced American journalist Danny Fenster to 11 years in prison for three charges, his employer reported on Friday.

Frontier Myanmar, the online magazine for which Fenster is managing editor, reported that the journalist was sentenced for incitement and violations of immigration and unlawful associations laws after a closed-door trial in a court inside Yangon's Insein Prison, where he is being held.

"The sentences imposed were the harshest possible under the law," it said.

The charges were based on allegations that Fenster was working for the Myanmar Now news outlet, which was banned by the military junta after the Feb. 1 coup, Frontier Myanmar said. However, it added that the journalist had left the outlet in July 2020 and had been working for Frontier Myanmar for nine months at the time of his arrest.

Frontier Myanmar said it had provided "a significant amount of evidence" of Fenster's employment, including tax and social security records and a testimonial.
