LONDON: Four British admitted in court on Wednesday to plotting to blow up the London Stock Exchange in 2010.

The men belonged to a group of fundamentalists who plotted a spate of mail bomb attacks during the run-up to Christmas that year and discussed launching a "Mumbai-style" atrocity, Woolwich Crown Court in London heard.

Mohammed Chowdhury, 21, and Shah Rahman, 28, both from London, admitted preparing for acts of terrorism by planning to plant an improvised explosive device (IED) in the toilets of the London Stock Exchange.

Brothers Gurukanth Desai, 30, and Abdul Miah, 25, both from Cardiff in Wales, admitted the same count.

Five others, four from the central city of Stoke and another from Cardiff in Wales, also admitted involvement in the group.

Police seized a hand-written target list that included the mayor of London, two rabbis and the US embassy during the arrests.
