Moscow - Play in the Rugby World Cup Sevens tournament was suspended on Sunday after a massive thunder storm over the Luzhniki Stadium.
New Zealand were leading Fiji 12-0 in the Cup semi-final when claps of thunder echoed around the stadium and bolts of lightning lit up a darkened sky.
Torrential rain followed, and South African referee Marius van der Westhuizen was left with no option other than to usher the two teams back into the changing rooms.
"The thunder storm around Luzhniki Stadium has temporarily halted this Cup semi-final in the men's tournament with New Zealand leading Fiji 12-0," the IRB said.
The winners of the All Blacks-Fiji clash will play the victors of the second semi-final to be contested by England and Kenya.
