The incident took place on the Ater-Porsa Road, about 35 km away from here in Madhya Pradesh.
"We have received reports from the spot that five persons -- two men and three children -- were killed when a bus carrying a marriage party came in contact with a high tension line and caught fire," Deputy Inspector General (Chambal Range), D K Arya told PTI by phone.
The death toll may increase as the bus was carrying nearly 50 people and was totally gutted in the mishap.
