The death toll from the collapsed building in Bangladesh that housed several garment factories has risen to 147.
Rescue officials say emergency personnel continue to dig through the rubble at the Rana Plaza shopping center in the Dhaka suburb of Savar, to find people who remain trapped in the debris.
One firefighter told Reuters there were about 2,000 people on the upper floors of the building at the time of its collapse. Survivors say the collapse happened within minutes.
Police officials say the factory owners appeared to have ignored a warning not to allow their workers into the building after inspectors discovered cracks in it on Tuesday.
Buildings in and around Dhaka often do not comply with construction regulations. Dozens of people died when a garment factory collapsed in the same area eight years ago.
