Jaipur/Indore, Jan 14: Two trucks went up in flames, after a spark caused a huge ball of fire on Jaipur-Ajmer highway on Friday. 

The Indian Oil trailer was carrying 32 tonnes of PTA, an inflammable chemical from Panipat.

Sparks from a welding work being done near the roadside caused the fire. A bus and two motorbikes also caught fire, but the flames were doused.

In Indore, an electrical short circuit caused a fire which gutted a car completely. The driver escaped.
