Washington – The US says Indonesia must hold its armed forces accountable for rights violations after three soldiers accused of torture received only 8 to 10 month jail terms.

Footage of the torture of two Papuan men was posted on YouTube last year. It showed the soldiers burning the genitals of one unarmed, naked man and running a knife across the neck of another.

The judge at the military tribunal which passed sentence Monday said the soldiers deserved some leniency because they had confessed to their crimes and shown remorse.

State Department spokesman P.J. Crowley said Tuesday the sentences did not reflect the seriousness of the abuses depicted in the video.

Crowley said in a post on Twitter the US was "concerned and will continue to follow this case."
