Four men guilty of botched 2005 London bomb plot

LONDON (Reuters) - Four men were convicted on Monday of plotting to bomb London's transport system on July 21, 2005 in a botched attempt to replicate Islamist suicide bombings that had killed 52 people two weeks earlier. 

Police said the men, Muslims of African origin, would have caused carnage on a similar scale to the attacks a fortnight before but although the detonators on their makeshift bombs fired, the main charges failed to explode.
