An Unidentified Flying Object, or UFO, passed across the large north-western Chinese city of Lanzhou and apparently exploded in the suburbs, state media said on Monday.

    The unusual sighting of two bright trails of light, reported by several witnesses, took place last Saturday shortly before midnight, the China Times reported.

    Police, working on the theory that it was a meteorite, went to investigate the matter, but as of today they had found no evidence of what caused the nightly phenomenon, an officer told AFP by telephone.

    A taxi driver told the paper he was in his car when everything suddenly became "as bright as day."
