Savar Rana Plaza Tragedy -- 24th April 2013

The 2013 Savar building collapse or Rana Plaza collapse was a structural failure that occurred on 24 April 2013 in the Savar Upazila of Dhaka District, Bangladesh, where an eight-story commercial building named Rana Plaza collapsed. The search for the dead ended on 13 May 2013 with a death toll of 1,134. Approximately 2,500 injured people were rescued from the building alive. It is considered the deadliest structural failure accident in modern human history, and therefore also the deadliest garment-factory accident in history. The building contained clothing factories, a bank, apartments, and several shops. The shops and the bank on the lower floors were immediately closed after cracks were discovered in the building. The building's owners ignored warnings to avoid using the building after cracks had appeared the day before. Garment workers were ordered to return the following day, and the building collapsed during the morning rush-hour.
