Vladimir Putin reportedly suffered a middle-of-the-night "health scare" early on Saturday.
Doctors were summoned to the Russian leader's presidential quarters after he complained of severe nausea, and was given "urgent medical care".
The claims, which have not been confirmed by the Kremlin, but have been reported after they were made by the General SVR Telegram channel which has been monitoring the president's health. The channel asserts he has serious medical problems which have not been officially disclosed.
