At least 17 construction workers have died and many others have faced exploitation and labor abuses while building stadiums for the 2018 World Cup in Russia, according to a report by Human Rights Watch.

The report also said that FIFA, soccer’s corruption-plagued governing body, lacked transparency and had failed to demonstrate that its monitoring system had effectively identified, prevented and corrected stadium labor conditions.

“FIFA is still in its post-corruption catharsis, but this feels, unfortunately, like more of the same mode,” Jane Buchanan, the author of the Human Rights Watch report and a researcher on Russia, said in an interview. She was referring to the flurry of arrests of international soccer officials in 2015 on charges of racketeering, wire fraud and money laundering.

The 34-page report, set to be made public Wednesday, appears to be the most comprehensive analysis so far of the labor situation ahead of the World Cup, which will be contested at 12 stadiums in 11 cities across Russia from June 14, 2018, to July 15.
