Final death toll of Italy hydroelectric plant blast rises to seven

Italian rescuers have found the bodies of the last two missing workers from an explosion at a hydroelectric plant near Bologna three days ago, a spokesperson for the fire brigade said on Friday, bringing the final death toll to seven.

On Tuesday, a fire that broke out on a transformer and the subsequent blast rocked the plant on the shores of the artificial Lake Suviana, owned by Enel Green Power, a unit of utility group Enel.

The explosion has heightened concerns by trade unions about workplace safety in Italy, where over 1,000 people lost their lives while working last year, according to a report by the country's national workers' compensation authority INAIL.

Divers recovered the bodies from the ruins of a turbine hall some nine levels -- 40 metres or so -- below the lake.

Rescue efforts were interrupted in the late morning of Friday after the last corpses were found, the spokesperson added.

The cause of the accident has not been established and Italian prosecutors have launched an investigation, as is mandatory in such cases.
