B Raman, an expert on Al Qaeda, told rediff.com: "This is the first and only instance of a Muslim person of Indian origin who is found to be associated with Al Qaeda. Otherwise Al Qaeda had met with no success. In this case too he is a convert."
The eight were arrested two weeks ago in countrywide raids conducted by police and intelligence agencies.
The men, charged with conspiring between January 1, 2000 and August 2004 under the Criminal Law Act, 1977, were dressed in casuals and stood silently in the dock as the charges were read out.
Dhiren was charged with possessing reconnaissance plans for the New York Stock Exchange, the International Monetary Fund, Citigroup building and the Prudential building and possessing notebooks containing information on explosives, poisons and chemicals.
Another man, Matthew Monks, 32, of Sudbury, London, held with the eight on August 3, appeared at the court charged with possession of a prohibited weapon, but was released on bail.
