A series of letter bombs that have caused several injuries across the UK were designed to shock rather than kill, say British police. The latest device was received with the morning post at an office in Swansea, South Wales. Although the letter bombs contained small pyrotechnic charges rather than explosives, eight people have sustained minor injuries.
There have been seven cases in six different towns in the last three weeks. No-one has yet claimed responsibility. The last three, in Swansea, Berkshire and London, were all sent to motoring-related offices, fuelling speculation that the culprit may be a driver bearing a grudge. But earlier packages were reportedly linked by police to animal rights activists. Authorities are calling for people to be vigilant.
