Construction workers at the World Cup football stadium in the Brazilian city of Manaus have gone on strike demanding better safety conditions.
The builders’ union took the action after a worker fell more than 35m (100ft) to his death on Saturday.
All high work had already been halted by a court order on the weekend. It is not clear when the contractors will resume work.
Half of the 12 stadiums being built for the tournament are behind schedule.
The workers at Arena Amazonia say pressure to finish the construction is affecting their safety.
