Human Rights Watch (HRW) says hundreds of Sudanese men reportedly recruited by an Emirati security firm as guards in the United Arab Emirates (UAE) have been tricked into fighting in Libya for renegade military commander General Khalifa Haftar.

The New York-based organization announced in a report that Black Shield Security Services hired more than 390 Sudanese men, who thought they were coming to work as security guards in the wealthy Persian Gulf country.

They expected to be posted in malls, hospitals, hotels, or at the entrance of embassies or government buildings.

Upon arrival at Abu Dhabi International Airport, a group of more than 40 Sudanese men were met by two Emirati men, who introduced themselves as representatives of Black Shield Security Services, according to Human Rights Watch.

The company representatives immediately confiscated the men’ passports – a pervasive practice in the UAE despite official prohibition since 2002. The men then boarded buses and were taken to a compound in the city of Ghiyathi, situated about 300 kilometers (186 miles) to the east.
