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.

The workers at Arena Amazonia say pressure to finish the construction is affecting their safety.
