LAHORE, Pakistan (AP) — The death toll from the collapse of a four-story factory building in eastern Pakistan rose to 20 on Thursday, as rescuers with cranes and construction equipment continued digging for survivors, officials said. Rescuers had pulled 102 people from the rubble alive and dozens of experts from the army and hundreds of civilians were looking for those who remain missing, said Jam Sajjad Hussain, a spokesman from the state rescue agency.
