A Brazilian labor court has allowed construction to fully resume at the Arena da Amazonia World Cup stadium, where two workers died Saturday.

Work was halted at raised areas of the stadium Sunday after one worker fell 35m to his death and another died of a heart-attack.

Judge Margarete Dantas Pereira Duque Wednesday ruled that the company responsible for the project, Andrade Gutierrez, had taken the necessary measures to ensure workers' safety.

Construction remains prohibited on the stadium's roof at night.

Stadium officials said a new working schedule for the venue would be submitted to authorities within five days.

Saturday's incidents took to six the number of deaths at Brazil's 2014 World Cup stadiums.

Arena da Amazonia will host four World Cup matches next June and July.
