The United Arab Emirates shocked Russia in a 4-1 win to throw Group C wide open.
UAE caught Russia off guard from the start with keeper Mohamed Aljasmi scoring from well over 30 metres with a well-executed low drive that caught a hard angle in the sand before evading Russia keeper Maksim Chuzhkov.
Artur Paporotnyi equalised for Russia when Boris Nikonorov teed him up to unleash a powerful curling shot into the bottom corner midway through the second period.
That was before Ali Mohammad put UAE back in front from the penalty spot, which saw them take a one-goal lead into the interval once again.
Hesham Muntaser and Waleed Beshr put the result beyond doubt, adding two more goals to the tally to see UAE defeat a European team at the Beach Soccer World Cup for the first time in history.
