Nursultan Nazarbayev's authoritarian government cracked down on critical news coverage with a flurry of early-year legislation and newsroom raids that came just weeks after deadly clashes between police and striking oil workers in the western city of Zhanaozen. In January, in the wake of the December 2011 labor unrest, Nazarbayev's government enacted legislation barring distribution of print or electronic news that the authorities deem a threat to national security. The authorities also imposed new regulations that require Internet café managers to block access to blacklisted websites and proxy servers, monitor client activity, and share client information with government security services. A third measure requires international broadcasters airing programming in Kazakhstan to register with the state. The government also deployed KNB security agents to harass news media that covered the violent crackdown against the strikers, which left 16 civilians dead. Agents raided the independent broadcaster Stan TV, demanded its recorded material concerning Zhanaozen, and interrogated its 15 journalists about the clashes. The KNB also detained editor Igor Vinyavsky for several weeks and intimidated his family and colleagues when they denounced the arrest. In November, just weeks after Kazakhstan was elected to the U.N. Human Rights Council, authorities asked the courts to shut dozens of critical news outlets on extremism and mass disorder charges in connection to their reporting on Zhanaozen clashes. Unknown assailants shot and stabbed Lukpan Akhmedyarov, an award-winning journalist who had criticized official actions in Zhanaozen. He was among five critical news reporters who were brutally attacked in separate assaults during the year. All of the attacks remained unsolved in late year.
