Dozens pulled alive from Dhaka factory as toll hits 256
Screams filtering through the cracks in the concrete suggest more survivors awaiting help

Dozens of workers were found alive on Thursday as they huddled in the wreckage of a collapsed garment factory bloc in Bangladesh, a rare success for rescuers who have pulled out 251 bodies.
In an announcement greeted by wild applause from thousands of relatives at the scene, an army spokesman initially announced that 40 survivors had been discovered together in a room, but the figure was later revised to 24.
Screams filtering through the cracks in the concrete suggested more survivors were awaiting help, but a steady stream of bodies saw the recorded death toll almost double on Thursday and hundreds remain unaccounted for.
Working with floodlights and hand torches, rescuers crawled through the cracks and pulled out three woman garment workers alive from the rubble at 11.30pm Bangladesh time, fire service director Mahbubur Rahman said.
"We’ve also located several pockets inside the wreckage where many people are still trapped. We could hear their screams. They were given food, water and oxygen."
