Apple has rejected accusations from Russia's state competition watchdog that it fixed iPhone prices.
The Federal Anti-Monopoly Service (FAS) said it was investigating "signs of price-setting coordination" among iPhone resellers following a complaint from a member of the public.
Apple told Reuters it did not control its products' pricing.
"Resellers set their own prices for the Apple products they sell in Russia and around the world," it said.
A citizen told the FAS that the iPhone 6s and iPhone 6s Plus, which went on sale in Russia in October 2015, were priced identically across all 16 major Russian retailers.
Five of the retailers have denied the claims.
The FAS said in a press release it suggested the price-setting was coordinated by Apple, leading to obligatory recommended prices.
