Rejecting the preliminary report on the fire at the garments factory in Karachi's Baldia town, Malik said investigators were probing the fire keeping the terror factor in mind and they were also examining some other aspects of the tragic incident.
Talking to the media during a visit to the factory site, the minister said there was evidence that the fire started because of a generator malfunction or short circuiting.
"Fires on the same day at two factories in Karachi and Lahore could be an act of terrorism," he added.

Malik said the garments factory had caught fire twice in the past and yet the owners had made no safety arrangements. He said an insurance claim for a previous fire at the factory was also being investigated.

The owners, who have obtained preventive bail until September 21, also recorded their statements with the police at an unknown location yesterday.
The owners have promised to compensate the victims and affected families.
