The venue of the 2022 FIFA World Cup is again under the spotlight after two Nepalese-British human rights workers disappeared in Doha.

According to the Norwegian NGO Global Network for Rights and Development (GNRD), its employees, Krishna Upadhyaya, 52, and Ghimire Gundev, 36, went missing on August 31 while they were working in the gulf state, reported the CNN.

A spokesperson for the UK embassy in Doha confirmed that an investigation had been launched into the disappearance of the two persons.

Qatar's Interior Ministry however, was unavailable for comment, the report said.

Upadhyaya, a human rights researcher and Ghirmire, a photographer, had arrived in the country on August 27 and had been preparing a report on the working conditions of migrant workers at the 2022 FIFA World Cup venue.

The 52-years-old researcher had checked out of the hotel after revealing to a friend in Norway that he felt unsafe but never boarded the flight. The GNRD confirmed that Upadhyaya was alarmed by the number of policemen in the vicinity and had said that undercover cops came very close to him whenever he spoke on the phone

Qatar had earlier hogged the limelight after revelations were made about migrant laborers working under inhuman conditions at the construction sites of 2022 World Cup facilities in Qatar.
