Defendants, accused of participating in December 2011 clashes in the oil town of Zhanaozen, look out from a glass cubicle during a court session in the Caspian port city of Aktau, March 27, 2012. Angry relatives of the accused burst into a Kazakhstan courtroom shortly before 37 people were due to go on trial on Tuesday for their role in deadly oil town riots that shattered the image of stability in the oil-producing Central Asian state.
