Norway, which has previously provided TV viewers with five hours of live knitting, a fire burning itself out and minute-by-minute salmon fishing, has found a new attraction - a rockslide on a mountain - but no-one knows when it will happen.

For days, local media have focused webcams on an isolated, rubbly mountainside in Mannen, western Norway, and national broadcaster NRK is streaming it live on its website in anticipation of the big event.

Last week, 11 people were evacuated from the area, now declared a no-go zone.

But the webcams cannot guarantee a good show. The slide might happen at night, and a daytime slide could be hampered by thick rain and mist.
