Prafulla Dinesh Bagda set her three daughters -- Nishanta (12), Bhavyata (8) and Astha (4) -- ablaze before torching herself at their residence this morning, police said.
The four were rushed to Rajkot Civil Hospital where Bhavyata and Astha were declared dead while Prafulla and Nishanta were stated to be critical, police said.
Police suspect that domestic quarrel might have led Prafulla to take such a step.
A complaint has been registered and further investigation is on, police added.
