A plane flying from the Turkish resort of Antalya to Vladivostok in Russia's Far East made a emergency landing in the Siberian city of Krasnoyarsk.
An Azur Air Boeing 767 requested an emergency landing while over Krasnoyarsk after experiencing problems with the hydraulics, Russia's Interfax news agency reported.
There were no reports of anybody being hurt.
The number of passengers and crew abroad the plane was not yet available. Boeing 767s can seat more than 200 passengers.
Azur Air is a former regional Russian airline that now operates charter flights.
An Azur Air flight leaving Antalya on September 10 on its journey to the Russian city of Belgorod, about 580 kilometers south of Moscow, initiated an emergency descent after a cabin-pressure alert, air-safety publication Aviation Herald reported.
That plane, a Boeing 757, returned safely to Antalya and a replacement Boeing 767 flew to Belgorod after a delay, according to the report and flight-tracking website Flightradar24.
Azur Air did not immediately respond to Russian media requests for comment.
Antalya on Turkey's Mediterranean is one of the most popular resort destinations for Russians.
