'At least 35 people killed in Genoa bridge collapse'

At least 35 people were killed when a bridge collapsed in the Italian port city of Genoa, police said on Wednesday after firemen worked through the night looking for any survivors buried under the rubble.

"The latest official number is 35 but we can't rule out it could rise further," a spokeswoman for the police in Genoa said.

The disaster occurred on a highway that connects Italy to France and other vacation resorts on the eve of a major Italian holiday tomorrow, Ferragosto, and traffic would have been heavier than usual as many Italians travelled to beaches or mountains.

The transport minister, Danilo Toninelli, called the collapse "an enormous tragedy."

The private broadcaster Sky TG24 said that a 200-metre section of the Morandi Bridge collapsed over an industrial zone.

Firefighters told The Associated Press that there are concerns about gas lines.

Photos published by the ANSA news agency on its website showed a huge gulf between two sections of the bridge.

Video captured the sound of a man screaming: "Oh god, oh, god." Other images showed a green truck that had stopped just metres short of the gaping hole in the bridge.

Interior Minister Matteo Salvini said some 200 firefighters were responding to the accident.

"We are following minute by minute the situation for the bridge collapse in Genoa," Salvini said on Twitter.

The Morandi Bridge was inaugurated in 1967. It is 90 metres high, just over a kilometre long, with the longest section between supports measuring 200 metres (yards).

The bridge is the main thoroughfare connecting the A10 highway that goes toward France and the A7 highway that continues north toward Milan.

ANSA said that authorities suspected that a structural weakness caused the collapse today.
