tornado 2 London Whole rows of terraced houses were left without roofs and cars had been tipped on their sides. Most of the injured suffered from cuts and bruises "It went dark and there was this incredible wind," Les Hampstead told the Daily Express. "The roof came crashing down. There's nothing left of the top of my house," the 51-year said. Birmingham City Council said parts of the affected areas remained cordoned to allow building surveyors to assess property damage. "They will determine whether people will be allowed back to their homes or whether remedial work is needed to make the properties safe," a spokeswoman said. According to the Met Office weather forecaster, tornadoes are not uncommon in Britain, but are rarely as severe as Thursday's. The damage was estimated to run into millions of pounds and the clean-up operation may take several days.
