Workers at a World Cup stadium in the jungle city of Manaus are threatening to go on strike to demand better conditions following the most recent death at the venue.
The strike could delay the completion of the Arena da Amazonia stadium just months before football's showcase tournament.
A union leader says the stoppage will begin Monday to "guarantee the workers' rights".
A 55-year-old Portuguese man was killed in an accident on Friday while disassembling a crane that was used to install the stadium's roof. It's the third worker's death at the venue in less than a year.
The Arena da Amazonia is one of the five stadiums still under construction for the World Cup. Organisers say it was nearly completed when Friday's accident happened.
It will host four World Cup matches next June, including England vs. Italy and the United States vs. Portugal.
