Rescuers continued to search through the rubble of an eight-story building Wednesday night after it collapsed near Bangladesh's capital, Dhaka, killing up to 194 people at last count and trapping hundreds.
Authorities estimated about 2,000 people were inside the building, which housed several garment factories and a shopping center, when the devastation occurred at about 9 a.m., Reuters reported.
The Associated Press reported 3,122 garment workers were employed to work in the building, though it's not clear how many of them were at work at the moment of the collapse.
According to Reuters, more than 1,000 people were injured.

As fire fighters and army personnel worked frantically Wednesday to find survivors, reports said tens of thousands of onlookers gathered at the Rana Plaza building in Savar, 19 miles outside Dhaka.
One survivor described how the building collapse came without warning, the Associated Press reported.
"It collapsed all of a sudden," a 25-year-old worker named Sumi told the AP. She said she had been sewing jeans on the fifth floor with at least 400 others when the building crumbled.
"No shaking, no indication. It just collapsed on us," she said to the AP.

One of the companies operating in the building was the New Wave Button factory, the Wall Street Journal said. The AP reported that New Wave Style Ltd. and New Wave Brothers Ltd. garment factories were housed in the building, as well as Phantom Apparels Ltd.
Phantom Apparels' website, whose metadata indicates that the company is a joint Spanish-Bangladeshi venture, confirms the address. The 24-hour garment operation exports to Italy, Germany, Netherland, Spain, Sweden, Denmark, and the US, according to Vero Style Limited, a garment manufacturer based in Bangladesh.
The tragedy follows last year's garment factory fire in Bangladesh, which killed at least 122 and led to the Bangladeshi government declaring a day of national mourning on November 27.
