Five men appeared in court today charged with terror offences after being arrested in a series of raids in Birmingham nine days ago, while a sixth was charged later under the Terrorism Act.
One of the defendants, Parviz Khan, is accused of plotting to kidnap and kill a British soldier.
The other four, Amjad Mahmood, Mohammed Irfan, Zahoor Iqbal and Hamid Elasmar, also face offences under the Terrorism Act.
The five defendants were flanked by eight security guards as they filed into the dock at the City of Westminster magistrates court.
Two of the men - including Mr Khan - remained standing throughout the hearing.
They listened intently throughout the hearing before district judge Daphne Wickham.
No applications for bail were made on behalf of Mr Khan, Mr Mahmood or Mr Elasmar and they were remanded in custody until February 23, when they will appear at the Old Bailey.
Later, the judge refused a bail application made on behalf of Mr Iqbal. He was also remanded in custody until February 23, as was Mr Irfan, whose application for bail was withdrawn.
Earlier today, the defendants were transferred from Coventry to London in a police convoy.
This morning, the Crown Prosecution Service confirmed that Mr Khan was accused of plotting to kidnap and kill a member of the British armed forces.
The 36-year-old was accused of engaging in conduct "to give effect to his intention to kidnap and kill a member of the British armed forces" between November 1 last year and the time of his arrest last week, the head of the CPS counter terrorism division, Sue Hemming, told a press conference at West Midlands police headquarters.
Mr Khan was also charged with attempting to supply equipment for use in terrorism acts and making available funds or property which could be used for terrorism acts.
Mr Irfan, 30, and Mr Elasmar, 43, were each charged with one offence under the Terrorism Act 2006 and one offence under the Terrorism Act 2000. Mr Mahmood, 31, was charged with two offences under the Terrorism Act 2000 and one offence under the Terrorism Act 2006.
A sixth man had been charged under the Terrorism Act, police said this evening.
Two of the nine suspects arrested last Wednesday were freed without charge earlier this week. A third was released without charge today and another man remains in custody. He must either be charged, released or police must be granted court permission to continue detaining him by 4am tomorrow.
The West Midlands Assistant Chief Constable, David Shaw, said the inquiry had made "extraordinary progress" since the arrests nine days ago. More than 4,500 exhibits had been seized, including computers and mobile phones, though most had yet to be examined.
Mr Shaw said that despite the demand on police resources of the "very significant operation", the force had continued to provide services to all its neighbourhoods. He also thanked a number of organisations, including MI5 and the Metropolitan police, for help during the investigation.
"This has been more than just a police operation. Birmingham city council has played a part in working with us to help communities in these difficult times," Mr Shaw said. "We have seen real leadership in all sections of the community."
