A bridge carring a four-lane state highway in the US city of Minneapolis has collapsed during rush hour with dozens of cars and lorries falling into the Mississippi River. A kilometre-long section of the 35W bridge buckled and fell 40 metres into the water just after 6 pm local time. The media are reporting at least seven deaths. At least sixty people have been taken to hospital. The structure is not yet stable and there are fears of further collapse. Several vehicles are also on fire and there are reports that a freight train passing underneath was been crushed by the impact. The US Department of Homeland Security has said there is no reason to believe the incident is terrorist-related. However, it is understood a programme of repair work was being carried out at the time of the tragedy.
