Five teenagers from London have been remanded in custody charged with terrorism offences.
Four of the male teenagers are alleged to have planned to travel to Syria to join so-called Islamic State (IS).
All four are accused of plotting to carry out acts of terrorism abroad.
A fifth boy, aged 15, is accused of having terrorist materials, including IS publication Inspire and a bomb-making video.
Those charged are:
- A 17-year-old from Merton, charged with preparation of terrorist acts and collection of information
- A 16-year-old from Lambeth, charged with preparation of terrorist acts
- A 17-year-old from Hounslow, charged with preparation of terrorist acts and dissemination of terrorist publications
- A 15-year-old from Waltham Forest, charged with collection of information and two counts of dissemination of terrorist publications

All five appeared at Westminster Magistrates' Court on Saturday.
Mr Alsyed, the two 17-year-olds and the 16-year-old will next appear at the Old Bailey on 17 March.
The 15-year-old appeared pleaded not guilty to the charges against him. He will stand trial on 2 May at the same venue.
Mr Alsyed is the only suspect who can be named, owing to the ages of the others being held.
