Kullu: While UFO sighting has been reported from Lahaul and Spiti several times in the past, this time a more near-earth phenomenon has spread panic in a small hamlet some distance from district headquarters Kaza. On July 27 people in Rangrik village claimed to have heard and seen an explosion atop a nearby hill top, which they claimed was similar to volcanic eruption. This was followed by landslides and water gushing out of the hill continuously.
