ATYRAU, Kazakhstan -- The trial of 47 men charged with terrorism has ended in the western Kazakh city of Atyrau .
The court on April 18 sentenced 42 of them to prison terms from 6 to 12 years for creating a terrorist group and preparing or carrying out explosions in Atyrau and other towns in the region.
RFE/RL's Kazakh Service reports that the other five men were sentenced to prison terms from 5 to 15 years on April 2.
