I found this article about the strike on the CommonDreams Progressive Newswire:
http://www.commondreams.org/news2000/1101-03.htm
It describes the conditions, Human Rights Watch's intervention and well as the strike and the improvments made after.

This link goes to a Media Alert for a Press Conference describing the conditions being protested as well as a solidarity march for the detainees around the time of the strike.

I hope this helps!
