Bangladesh announced murder charges on Monday against 41 people including the owner of a building that collapsed in 2013, Sohel Rana, and his parents and more than a dozen government officials for their direct role in the deaths of 1,137 people.
The collapse of Rana Plaza was Bangladesh's worst industrial disaster and sparked an outcry for tougher safety regulations in the country, which is the world's second-largest garment exporter.
The accident has also reopened the debate about poor working conditions in developing countries that produce goods for big international retail companies.
The owner and the other defendants are accused of ignoring warnings before the accident and of keeping the workers inside despite a big crack in the building. A police report described the incident as "mass killing," which also caused nearly 2,500 injuries.
A hearing will take place June 28 to decide on further proceedings. If convicted of murder the defendants could face the death penalty.
