Security forces in Kazakhstan say they have killed dozens of anti-government rioters in an operation to restore order in the main city, Almaty.
They moved in after protesters tried to take control of police stations in the city, a police spokeswoman said.
Eight members of the security forces were killed earlier in the unrest, which was sparked by a doubling in the cost of liquefied petroleum gas (LPG).
Russia is sending in troops at the request of the Kazakh president.
They will be deployed to help “stabilise” the country, which is a member of the Collective Security Treaty Organization (CSTO) along with Russia, Belarus, Tajikistan, Kyrgyzstan and Armenia.
Protests began on Sunday when the government lifted its price cap on LPG, which many people use to fuel their cars, but the unrest has since spread to include political grievances.
