The total number of workers killed while trying to complete Brazil's stadiums for the World Cup now stands at eight.

This is just another setback in the country's bid to have the construction completed on time.

Muhammed-Ali Maciel Afonso was installing communications equipment at the Arena Pantanal in the western city of Cuiaba when he was electrocuted.

Work was halted temporarily.

Many projects have suffered due to poor resources and some key transportation projects have been abandoned altogether.

Two workers were killed in preparation for the South Africa World Cup in 2010.

Fifa secretary general Jerome Valcke and Brazilian sports minister Aldo Rebelo both sent their condolences to Mr Afonso's family, as well as his colleagues at Etel Engenharia.

The Arena Pantanal held a test match last month but the venue is one of the most-delayed of the tournament, with seating and wiring yet to be finished.

A fire in October caused structural damage, although that has since been repaired.

Critics warn the 40,000-seat venue could be one of the tournament's biggest white elephants, given that Cuiaba's biggest football team normally plays in front of crowds of just 2,000.
