Fire brigade divers are continuing the search on Friday for the remaining worker who is missing, feared dead, after Tuesday's explosion at Enel Green Power's Bargi hydroelectric plant on Lake Suviana. The death toll of the disaster climbed to six on Thursday when the divers found the bodies of three people who had been unaccounted for.

Five people were killed in the explosion at the power station on Tuesday. The bodies of two of the victims were found immediately after the disaster. The other two were found on Thursday and are in a critical condition in hospital. The search for the missing worker is expected to take several more days, fire brigade officials said on Friday. The incident happened at the Bargi power station, on the shores of Lake SuViana, in northern Italy. The power station is owned by Enel, which also operates the nearby Bargi Dam. It is the largest hydroelectric power station in the world, with a capacity of more than 1,000 megawatts.
