This is the horrific moment an acrobat fell 20ft during a daring circus act with his twin brother that left him with grave injuries.
Anton Martynov, 33, suffered two breaks in his spinal cord and a serious head injury in the spectacle in the Mstislav Zapashny circus show in the city of Elista in Russia.
The crowds moments earlier cheered when the duo swung from a cable that rises from the ground and hauls the pair gracefully to the ceiling.
But a massive gasp is heard when Anton crashes down when the rope he is attached to can be seen un-ravelling.
