At least 164 people have died in Kazakhstan during violent anti-government protests, according to media reports citing health officials.
If confirmed it would mark a sharp rise from the previous figure of 44 deaths.
The demonstrations, triggered by a rise in fuel prices, turned into huge riots as they spread across the country.
They started on January 2 and grew to reflect discontent at the government and former President Nursultan Nazarbayev, who led Kazakhstan for three decades and is still thought to retain significant influence.
A state of emergency and a nationwide curfew remain in place.
Some 103 fatalities in the latest violence were reportedly in the main city, Almaty.
