A plan to strike high profile targets in London in 2010 with improvised explosive devices and nail bombs has been admitted in court by four men.
The London Stock Exchange was earmarked where the four intended to plant a bomb in the toilets.
A hand written list of potential targets included the home of London Mayor, Boris Johnson while the US Embassy was also identified.
The men Mohammed Chowdray and Shah Rahman from London, Gurukanth Desai and Abdul Miah from Cardiff admitted a range of terrorism offences. They changed their plea to guilty before the court appearance.
Undercover officers had followed them as they went around London on a recce of some of the capital’s landmarks including the London Eye.
The defendants had been inspired by the recently-killed radical Muslim cleric Anwar al-Awlaki.
The judge told them they could expect to receive up to 18 years. Five other men admitted lesser terrorism charges.
