Parviz Khan, 37, of Birmingham, concocted a plot to lure an unnamed British Muslim soldier into a trap, using cocaine, prosecutors said at Leicester Crown Court, about 100 miles (160 kilometres) north of London.

'He would be taken to a lockup garage and there he would be murdered by having his head cut off like a pig,' prosecutor Nigel Rumfitt said.

'This atrocity would be filmed ... and the film released to cause panic and fear within the British armed forces and the wider public.' Prosecutor Duncan Atkinson said Khan spoke about using cocaine as bait to trap the soldier.

Jurors were read a transcript in which Khan apparently refers to winning the soldier's interest 'by the white stuff.' 'Then afterwards we can ambush him or whatever,' Khan said, according to the document.

Khan had asked another man, Basiru Gassama, 30, to identify a victim. But Gassama, a Gambian citizen, never came up with the details and the plan 'lay dormant' after July 2006, said Rumfitt.

He said Khan revived the plot in November 2006.

Gassama pleaded guilty to a lesser charge of failing to disclose details of the plot.

Khan also admitted to sending equipment, including computer hard drives and night vision equipment, to terrorists operating on the restive Pakistan-Afghan border, prosecutors said.

Two others, Mohammed Irfan, 31, and Hamid Elasmar, 44, pleaded guilty to helping Khan supply the equipment.

The guilty pleas were made earlier this month but could not be reported until a trial involving two other men who pleaded innocent to the charges began on Tuesday.

Amjad Mahmood, 32, has pleaded not guilty to a charge of failing to disclose details of Khan's plot. Zahoor Iqbal, 30, pleaded not guilty to possessing the 'Encyclopedia Jihad' - a computer disk that prosecutors say could be useful to a terrorist.

Both Iqbal and Zahroor have also pleaded not guilty to helping Khan to supply equipment to terrorists.

The men were arrested in a series of raids in Birmingham in January 2007. -- AP
