BRIG, Switzerland, Dec 7 (Reuters) - An activist group erected protest billboards in FIFA boss Gianni Infantino's Swiss home town of Brig on Wednesday to demand the world soccer body compensate migrant workers for alleged human rights abuses in Qatar, host of the football World Cup.The mobile billboards carried the messages "Infantino: your family were migrants", "Thousands like them were victims of this World Cup", and "Compensate them now".Qatari World Cup organisers have said that there have been three work-related fatalities and 34 non-work-related deaths among workers at World Cup 2022 sites.Amnesty and other rights groups have led calls for FIFA to compensate migrant workers in Qatar for human rights abuses by setting aside $440 million, matching the World Cup prize money.The EU parliament last month approved a resolution that calls on FIFA to help compensate the families of migrant workers who died, as well as workers who suffered rights abuses, during preparations for the World Cup."
