The deposed leader has been sentenced to a total of 33 years in prison in different trials since the February 2021 coup.
The latest verdict, handed down in a prison trial in a purpose-built courtroom on the outskirts of the capital Naypyidaw, was announced by a justice official who insisted on anonymity for fear of reprisals from the authorities.
The trial was closed to the media, diplomats and Suu Kyi’s supporters, but her lawyers were barred from comment.
Suu Kyi has been the face of Myanmar’s democracy movement for more than 30 years.
The junta has promised to hold elections next year, but Suu Kyi may be prevented from participating in the elections due to her convictions.
Many of Suu Kyi’s political allies were also arrested after the coup. Thus, one of the cabinet ministers was sentenced to 75 years in prison.
The Burmese army seized power in the country on February 1 last year, overthrowing the government of Suu Kyi. The military junta represses democratic protests and persecutes opponents of the regime.
Information gathered by local activists shows that more than 2,200 civilians have been killed and more than 15,000 arrested as security forces have targeted the protest movement.
The military junta also puts pressure on the media, trying to control the flow of information. The internet is disrupted and local media licenses are revoked.
