A court has heard that three terrorism suspects were involved in a plot to behead a member of the British public "imminently" when they were arrested.
Nadir Ali Sayed, 21, from Hounslow, west London, Yousaf Shah Syed, 19, from High Wycombe, Buckinghamshire, and Haseeb Hamayoon, 27, from Hayes, west London, were arrested three days before Remembrance Sunday.
The trio were remanded in custody after a preliminary hearing at Westminster Magistrates' Court.
According to the BBC's home affairs correspondent, "Mr Sayed and Mr Syed stood in the dock for most of the proceedings, 'smiling and laughing as details were read out', while Mr Hamayoon remained seated." CNN reported that prosecutors said the men "were inspired by a speech from ISIS".
A fourth man had been arrested in west London, but was released without charge.
