Three men have appeared in court in central London on Saturday, charged with terrorism offences.
Metropolitan Police anti-terrorist officers charged the men
Roque Fernandes, 43, and Abdurahman Ranyare, 52, both from west London, and Dominic Martins, 44, of Middlesex, have been charged under the Terrorism Act.
They were remanded in custody to appear in court in November.
The charges follow arrests made after the News of the World newspaper provided information to police about alleged plans for a "dirty bomb".
Four arrests originally took place but one man was released without charge on Thursday.
It is alleged the three they "entered into, or became concerned in, an arrangement as a result of which money or other property was made available, or was to be made available to another, and knew or had reasonable cause to suspect, that it will or may be used for the purposes of terrorism".
The men will appear at Bow Street magistrates court on 1 November.
