Letters Bombs in Britain

The New York Times reported today (for the first time on the front page of its website, as near as I can tell) that a "3rd Letter Bomb Explodes in Britain in 3 Days."

It seems the British Police have been holding out as well:

Police disclosed today that four other letter bombs had been sent in January to other businesses, two of them providing forensic outsourcing services to the police. A letter bomb was also sent to the director of an outsourcing company providing services to a tax collection office in Folkestone, Kent, south of London.
