'Screaming for their lives': Pakistan factory fires kill at least 125 Rehan Khan / EPA A man tries to identify body of his relative at a mortuary following a huge fire at a garment factory in Karachi, Pakistan, Wednesday. KARACHI, Pakistan -- Fires swept through two factories in Pakistan, one in the city of Karachi and the other in Lahore, killing at least 125 people, officials said Wednesday. The death toll from the late Tuesday fires is likely to raise fresh questions about industrial safety in the nuclear-armed South Asian nation and draw more criticism of the deeply unpopular government. In the deadliest incident, flames raced through a garment factory in the teeming commercial capital of Karachi, killing at least 100 people. "People started screaming for their lives," said Mohammad Asif, 20.

In Lahore, a fire raged in a shoe factory, killing at least 25 people. Critics say Pakistan's government is too corrupt and ineffective to focus on the welfare of workers and a dizzying array of other problems, from crippling power cuts and widespread poverty to a Taliban insurgency. "The owners were more concerned with safeguarding the garments in the factory than the workers," said garment factory employee Mohammad Pervez, holding up a photograph of his cousin, one of the workers who is still missing. If there were no metal grilles on the windows a lot of people would have been saved. The factory was overflowing with garments and fabrics. Whoever complained was fired. The Guardian newspaper quoted an injured factory worker who survived as saying bars on the factory windows stopped the workers from escaping easily. "Some of us quickly took tools and machines to break the iron bars," he said, speaking from a hospital in Karachi, the Guardian reported. That's how we managed to jump out of the windows down to the ground floor. At a Karachi hospital, about 30 bodies burned beyond recognition were lined up at a morgue. There is no space left here. It's full," said ambulance worker Wasif Ali. They keep coming. Search is on for factory owners Senior Superintendent of Police Amir Farooqi told Reuters that police were raiding parts of Karachi to search for the factory owners. The latest death toll in Karachi was more than 100 people, said Farooqi. There were no safety measures taken in the building design. There was no emergency exit. All the people got trapped," Farooqi said according to the Guardian's report. Aid workers become targets as Pakistan faces new humanitarian crisis Smoke was still rising from the factory as rescue workers pulled out charred corpses and covered them in white sheets. Relatives of workers stood around in the street awaiting word of their fate. Several wept. "Within two minutes there was fire in the entire factory," said factory worker Liaqat Hussain, 29, from his hospital bed where he was being treated for burns all over his body. There was no access to get out, we were trapped inside. In Lahore, workers at the shoe factory suspected that the fire was caused by a problem with a generator. Al-Jazeera reported that the factory had been built illegally in a residential part of Lahore. US, Pakistan should 'divorce,' ex-ambassador to Washington says "We saw our colleagues burning alive, in flames," said Shabdir Hussain, from his hospital bed. We could do nothing. We saved our lives by jumping from the roof. Successive governments have been unable to provide a reliable power supply so factories have to have their own generators, powered by diesel or petrol, if they want to avoid regular, lengthy power cuts.
