UK ENGLAND LONDON 15APR10 - Airline passengers are stranded in London's Heathrow airport due all air traffic being suspended following a giant ash cloud entering UK air space. Flights have been disrupted across northern Europe by volcanic ash drifting south and east from Iceland.

Airspace was closed or flights cancelled in countries including the UK, the Republic of Ireland, Denmark, Norway, Sweden and Finland. The ash, which can damage aeroplane engines, was produced by a volcanic eruption under a glacier in Iceland.
