An eight-story building housing several garment factories collapsed near Bangladesh's capital Wednesday morning, killing at least 70 people and trapping many more in the rubble, officials said.

The collapse stirred memories of a fatal fire at a garment factory in November that killed 112 people and raised an outcry about safety in the nation's garment industry.

Workers in the Rana Plaza building said it had developed such severe cracks the day before that it had been reported on local news channels. They hesitated to enter the building Wednesday morning, said Abdur Rahim, who worked in a garment factory on the fifth floor.

But a manager from the factory assured them there was no problem, so they went inside, he said.
"We started working. After about an hour or so the building collapsed suddenly," he said. He next remembered regaining consciousness outside the building.

Tens of thousands of people gathered at the site, some of them weeping survivors, some searching for family members. Firefighters and soldiers using drilling machines and cranes worked together with local volunteers in the search for other survivors from the building.

An enormous section of the concrete structure appeared to have splintered like twigs. Colorful sheets of fabric were tied to upper floors of the wreckage, presumably so those inside could climb down and escape.
An arm jutted out of one section of rubble. The lifeless body of a woman covered in dust could be seen in another. A firefighter carried the body of what appeared to be a teenager from the area.
Rahim said his mother and father, who worked with him in the factory, were trapped inside.
"I have no idea what is going on," he said.

Among the businesses in the building were the Phantom Apparels Ltd., New Wave Style Ltd and New Wave Brothers Ltd. Garment factories. It also housed a bank and shops.
Health Minister A.F.M. Ruhal Haque said that by Wednesday afternoon 70 people had been confirmed dead in the collapse at the building in the Dhaka suburb of Savar. Brig. Gen. Mohammed Siddiqul Alam Shikder said another 600 survivors had been rescued.
Reports indicated the death toll could rise.
"We had sent two people inside the building and we could rescue at least 20 people alive. They also told us that at least 100 to 150 people are injured and about 50 dead people are still trapped inside this floor," said Mohammad Humayun, a supervisor at one of the garment factories.
The collapse happened about 8:30 a.m. and since garment factories in the area routinely work 24 hours a day, it appeared likely that the four housed in the building were staffed at the time.
The November fire at the Tazreen garment factory drew international attention to the conditions workers toil under in the $20 billion-a-year textile industry in Bangladesh. The country has about 4,000 garment factories and exports clothes to leading Western retailers. The industry wields vast power in the South Asian nation.
Tazreen lacked emergency exits and its owner said only three floors of the eight-story building were legally built. Surviving employees said gates had been locked and managers had told them to go back to work after the fire alarm went off.
The factory made clothes for Wal-Mart, Disney and other Western brands.
