"The news of blast at stone mining quarry in Karnataka is tragic. Condolences to the families of the victims. Such incidents call for in-depth investigation so that similar tragedies can be avoided in the future," the Congress MP from Kerala's Wayanad said in a tweet.
His remarks came after ten people were reportedly killed in the explosion.
Late on Thursday night, a loud sound of explosion was heard in Shivamogga, suspected to be caused by explosive materials kept on a stone crushing site, the police said, adding at least 10 people have been reportedly killed.
This incident took place in the Abbalagere village located along the Shivamogga-Hanagal state highway, which passes through Savalunga and Shikaripura.
Shikaripura, 290 km from Bengaluru, is the home constituency of Karnataka Chief Minister B.S. Yediyurappa.
