SAO PAULO (AP) — A worker at a World Cup stadium in Brazil died Thursday in an electrical accident, temporarily interrupting construction at one of the most-delayed venues only five weeks before the soccer tournament.

Rosenil Moraes, head of emergency services in the western state of Mato Grosso, said the construction worker received an electric shock at the site of Arena Pantanal in the wetlands city of Cuiaba. He died more than half an hour later of a cardiorespiratory arrest. Officials were not clear on what caused the accident.
