Four people have been killed and 20 others injured after a flash flood tore through a festival in northern Italy.
Reports from the scene talk of panic as a mud-filled torrent swept people away late on Saturday night at the festival at Refrontolo, north of Venice.
The event, by an old mill house beneath a waterfall, was meant to celebrate and promote the attractions of the area.
But during the festivities, there was a burst of very heavy rain and a wall of water suddenly ripped through the area.
According to the local media, some panic-stricken party-goers managed to cling to trees while the muddy torrent raged around them.
