Report: About 120 rescue workers are at the scene
The dead include 12 women and three men
Authorities suspect a boiler explosion caused the building's collapse
Eight people have been rescued from the rubble of the veterinary medicine factory, said Sarfraz Falki, a Lahore police official. Falki said 63 people were in the building when it collapsed, and rescue workers were continuing to try to reach any survivors. Authorities earlier had said 43 people were in the building when the explosion happened.
A boiler explosion apparently caused the veterinary medicine factory to collapse Monday, said Muhammad Salim, a Lahore police official.
In Pakistan, boilers are usually old and large, and building regulations in Pakistan are weak and often go unenforced, critics have said.
About 120 rescue workers were at the scene Tuesday, looking for survivors who may still be trapped in the building’s rubble, according to the Associated Press of Pakistan.
The 15 dead are comprised of 12 women and three men, the news agency said.
