Four Indonesian soldiers convicted of attacking human rights activist Andrie Yunus with acid have filed appeals against their sentences. The soldiers were previously sentenced to between 1.5 and 3 years in prison for the assault. Andrie Yunus is an activist with Kontras, a prominent human rights organization in Indonesia. The initial court ruling followed a trial that drew attention to allegations of military involvement in human rights abuses. Details regarding the grounds for the appeal have not yet been released. The case has been closely watched by rights groups concerned about accountability for violence against activists in Indonesia. This appeal marks the next stage in a controversial legal battle.
