Double Factory Blazes in Pakistan Kill 45 Factory fires in two of Pakistan's major cities killed 45 people and injured dozens more on Tuesday, including some who had to break through barred windows and leap to the ground to escape the flames, said officials and survivors. Workers recounted how their colleagues were trapped behind blocked exits, and firefighters said that one reason why the blazes were so deadly is that the buildings - a shoe factory in the eastern city of Lahore and a garment factory in the southern port of Karachi - lacked clear escape routes. Such safety issues are common through Pakistan, where buildings also lack emergency equipment like alarms and sprinklers and municipal rules are rarely enforced. The fire that swept through the four-story shoe factory in Lahore killed 25 people, some from burns and some from suffocation, said senior police officer Multan Khan. The factory was illegally set up in a residential part of the city. It broke out when people in the building were trying to start their generator after the electricity went out. Sparks from the generator made contact with chemicals used to make the shoes, igniting the blaze. Pakistan faces widespread blackouts, and many people use generators to provide electricity for their houses or to run businesses. One of the workers, Muhammad Shabbir, said he had been working at the factory for six months along with his cousin. He said all the chemicals and the generator were located in the garage, which was also the only way out of the building. When the fire ignited, there was no way out. Shabbir said he had just gone outside the factory when the fire started, but his cousin was severely burned and died at the hospital.

"The people went to the back side of the building but there was no access, so we had to make forceful entries and ... rescue the people," said Noor. Firefighters broke holes in the factory's brick walls to reach victims inside. At the morgue, bodies were lined up on a hallway floor, covered with white sheets. The second blaze at the garment factory in the southern port city of Karachi, the country's economic heart, killed at least 20 people, said the head of the emergency department at the Civil Hospital in Karachi, Tariq Kamal Ayubi. More than 40 others were injured, said another hospital official, Nazir Abbasi. All were workers at the factory. Pakistani television showed video of the five-story factory with flames leaping from the top-floor windows and smoke billowing into the night sky. Firefighters could be seen pounding on the metal grates covering some of the windows and pulling out smoke-covered bodies. Many of the workers were injured when they jumped from the burning building, said another doctor at the hospital, Karar Abbasi. One was a 27-year-old pregnant woman who had to leap from the second floor and was now suffering complications with her pregnancy, said hospital officials. An injured factory worker Mohammad Ilyas, speaking at the hospital, said he was working along with roughly 50 other men and women on one of the floors when suddenly a fireball came from the staircase. I jumped from my seat as did others and rushed toward the windows, but iron bars on the windows barred us from escaping. Some of us quickly took tools and machines to break the iron bars," he said. That was how we managed to jump out of the windows down to the ground floor. His leg was injured in the fall. Others weren't so lucky. An Associated Press reporter saw a charred body partially hanging out one of the factory's barred windows. It appeared the victim tried to escape but couldn't make it through the bars. Pakistani Prime Minister Raja Pervaiz Ashraf in a statement expressed his shock and grief over the deaths in both cities. Jawad reported from Karachi, Pakistan.
