At least 164 people have been in killed in the protests that have rocked Kazakhstan over the past week, according to a health ministry report.
Russian and state media broadcast the figure, citing a health ministry social media post.
But health and police authorities did not confirm the number, and the social media post was then deleted.
The internet has been restricted and telecommunications are patchy, making it difficult to check figures and confirm statements.
Kazakhstan's presidential office said that almost 6,000 people have been arrested, including "a substantial number of foreign nationals".
President Kassym-Jomart Tokayev’s office said Sunday that order has stabilized in the country and that authorities have regained control of administrative buildings that were occupied by protesters, some of which were set on fire.
The Russian TV station Mir-24 said sporadic gunfire was heard in Almaty on Sunday but it was unclear whether they were warning shots by law enforcement. Tokayev on Friday said he had authorized police and the military to shoot to kill to restore order.
Almaty’s airport, which had been taken by protesters last week, remained closed but was expected to resume operating on Monday.
Protests over a sharp rise in prices of LPG fuel began in the country’s west on Jan. 2 and spread throughout the country, apparently reflecting discontent extending beyond the fuel prices.
