NAIROBI, Kenya (AP) — The Eritrean government used forced labor to construct a gold mine it jointly owns with a Canadian company worth billions of dollars, an international human rights group said Tuesday.

The workers were transported to and from work in flat-bed trucks and were forced to work 12-hour-days, with a limited one hour midday break, Human Rights Watch said. They had Sundays off and were paid about $30 a month, the group’s report said.
