A Nepal-based human rights organization says over 400 Nepalese lost lives on World Cup stadium construction sites in Qatar.
The Pravasi Nepali Coordination Committee (PNCC), which follows up on migrant workers deaths in Qatar, recently published lists of the dead using official sources in the Qatari capital, Doha.
The PNCC also warned that the death toll can reach 4,000 by 2022.
The report will pile new pressure on the Qatari authorities and FIFA to curb the mounting death toll of foreign workers on the building sites.
Nepalese workers make up only 20 percent of two million migrant workers in Qatar and the death toll can be higher than this.
Migrants from other countries are also feared to have died, but there is no official data available.
