Prominent Kazakh opposition politician Zhasaral Quanyshalin has died of a heart attack at the age of 74 in a hospital in Almaty, his colleagues said late on May 18. Quanyshalin, who gained prominence in the late 1980s for his leading role in resolving a huge ethnic Kazakh-Russian conflict in the western city of Oral, was a lawmaker in 1994-95. He later became a staunch critic of the Kazakh government and tried several times to register a political party, but his attempts were denied. He unsuccessfully tried to register as a candidate for a snap presidential poll held in March. To read the original story by RFE/RL's Kazakh Service, click here.
