An explosion of a truckload of explosives, suspected to be meant for mining, killed at least six people in Karnataka's Shivamogga district on Thursday night and sent shockwaves in neighbouring areas, police said.

The massive explosion took place near a gravel and boulder crushing facility around 10.30 pm, sending shockwaves not only in Shivamogga, but also in neighbouring Chikkamagaluru and Davangere districts.
