Pilots in multiple Russian planes reported a UFO buzzing Volgograd when Vladimir Putin visited the city on Thursday.
The extraordinary accounts say the unidentified object ‘changed colour and height’ in the sky.
A report by Telegram channel Aviatorschina said the UFO was seen and reported to the aviation authorities by the crews of four separate passenger planes.
Putin had flown to Volgograd under close security to attend ceremonies linked to the 80th anniversary of the Battle of Stalingrad in the Second World War.
The incidents came as the dictator hinted that the conflict in Ukraine could turn nuclear following the West’s moves to supply Kyiv with major supplies of tanks.
He said: ‘We don’t send our tanks to their borders but we have the means to respond, and it won’t end with the use of armoured vehicles, everyone must understand that.
‘A modern war with Russia will be completely different.’
