New Delhi, Sep 12 (IANS): President Pranab Mukherjee on Saturday condoled the loss of lives due to twin explosions in Madhya Pradesh's Jhabua district and a train derailment in Karnataka.

"I am sad to know about the gas cylinder explosion this (Saturday) morning in Jhabua district in which a large number of people have lost their lives and many others are injured," he said in a message to Madhya Pradesh Governor Ram Naresh Yadav.
