Italian news reports say a motorized sled making a night run down an Italian ski slope slammed into a fence and flipped over into a ditch, killing six tourists and severely injuring two others aboard.

RAI state radio reported early Saturday that the sled's occupants were Russian tourists. The crash occurred on an unlit slope late Friday on Mount Cermis in northeast Italy. Victims' names were not immediately available. Cause of the crash was under investigation.

In 1998, a U.S. Marine jet, flying low on a training run from a nearby air base, accidently sliced a ski gondola's cable on Mount Cermis, sending the cable car crashing to the ground and claiming 20 lives.
