The son of a World Cup stadium construction worker who died in Qatar said his father warned of poor working conditions caused by excessive heat before his death in 2018.

Abdus Salam details how his father, Mosharraf Hossen, was "suffering to survive" in an interview with ESPN reporter Jeremy Schaap, as part of the E60 documentary "Qatar's World Cup" (ESPN/ESPN+, 8:30 p.m. ET on Nov. 6), which details the plight of migrant workers in the buildup to soccer's biggest tournament.

"He thought about the happiness and future of his family and went there with a hope of a better income," Salam said of his father, who moved from Bangladesh to Qatar in 2014 in search of work. "After getting the job [at the stadium], he said that 'They're not paying me properly. I am suffering to survive.'"

The summer heat in Qatar can reach 120 degrees Fahrenheit. On Aug. 8, 2018, the day after the temperature had reached 115 degrees, Hossen died.
