Four London teenagers accused of planning to travel to Syria to join Isis have appeared in court on terror charges.
The young men were said to be plotting to carry out acts of terrorism abroad.
Two of them are charged with going to the gym and paintballing as training for their plans while the other two are accused of buying flights and visas to Turkey and survival equipment.
They are all also accused of having extremist material and swapping messages online discussing how to get out to the war-torn country.
One of them allegedly had a video on his phone of battles, crusades and prisoners of IS being executed.
Another is charged with having details about how to build a pressure cooker bomb.
A fifth boy, aged 15, is accused of having terrorist materials, including IS publication Inspire and a bomb-making video.
All five appeared in custody at Westminster Magistrates' Court on Saturday, supported by their families.
A 16-year-old from Lambeth is charged with preparation of terrorist acts and a 17-year-old from Hounslow has been charged with preparation of terrorist acts and dissemination of terrorist publications.
Ahmedeltigani Alsyed, 19, of Hounslow, and a 17-year-old from Merton, are each charged with a count of preparation of terrorist acts and collection of information contrary to section 58 of the Terrorism Act 2000.
The four appeared together in the dock and were remanded in custody to appear at the Old Bailey on March 17.
The 15-year-old, of Waltham Forest, appeared in a separate youth hearing at the same court.
He pleaded not guilty to one charge of possession and two counts of dissemination of terrorist publications and is due to stand trial on April 19 at Westminster Magistrates' Court, sitting as a youth court.
He was remanded into the custody of the local authorities while living at his family address with a number of conditions, including a curfew, restricted internet access, supervision, weekly reporting to the police and a ban on international travel.
Four of the teenagers were arrested at addresses in south and west London on Tuesday while the 15-year-old boy was arrested on Monday evening in east London.
