Fear Grip Britons Over Series of letter Bomb Explosions

BRITISH police issued a public warning overnight after the latest in a series of letter bombs took the number of people injured to seven in five days, fuelling fears of a concerted bombing campaign.

Both Prime Minister Tony Blair and Home Secretary John Reid voiced concern over the attacks - several of which have targeted motoring-related firms - after the latest incident left three people injured in south Wales.

"Naturally, these incidents are worrying ... It is important that we allow police to get on with their investigation without undue speculation," Mr Reid said, in his first comments on the blasts.
