After a fire erupted at an oil depot in Sudhar Monday night at Faisalabad, five labourers were killed and five injured.
After five hours the blaze was put under control.
The fire erupted after a boiler broke due to the recklessness of a worker, the owner of the factory said.
According to the authorities, there were 12 to 13 employees inside the plant, after the fire erupted, adding that they have called for an initial fire survey. The exact cause remains to be ascertained.
