USA: A woman called Ms Crispi accused of starting a fire in her ex-boyfriend’s house with a pound of bacon is to stand trial on arson charges.

Several illuminated electronic devices planted at bridges and other spots scared Boston, and briefly disrupted the traffic and subway service, in what turned out to be a US publicity campaign for a late-night cable television cartoon.

Three-tonne concrete panels fell from the roof of Boston’s Big Dig cross-city tunnel, killing a woman in a car and shutting down a section of the massive US building project.
