A group of UFO enthusiasts gathered on the shore of Russia’s Lake Baikal on Tuesday (July 31) to search the sky above the world’s deepest lake for flying saucers.

The group, consisting of approximately 50 people, set up tents on the southern end of the lake as part of an event they’ve named the ‘Trans-Eurasian UFO-Search expedition’.

The UFO enthusiasts were drawn to lake Baikal, because locals have reported an increase in sightings of strange objects there.
