At least 63 people were killed when a blaze engulfed a garment factory in Pakistan's largest city Karachi, an official said on Wednesday.
"We have recovered 63 bodies, including three found when we reached the basement of the building. I fear more bodies could be there," Karachi fire chief Ehtesham Salim told agencies.
The death toll was revised sharply upwards after police earlier said the fire, which erupted late Tuesday, had killed nine workers and injured 20 others.
Earlier Tuesday, a blaze in Pakistan's second largest city, Lahore, trapped dozens of workers in a shoe-making factory, killing 21 workers and injuring 14 others.
