A 33-year-old man from Cardiff accused of terrorism offences, including plotting an offence by storing a computer operating system in a cufflink, has appeared in court.
Samata Ullah, from the Riverside area of the city, was charged on Tuesday with six terrorism offences including membership of Islamic State (IS) and the possession of a book about missile guidance and control.
Mr Ullah is also accused of giving "terrorist training", "directing terrorism", and "assisting another or others to commit acts of terrorism", by researching an encryption program and developing an encrypted version of his blog site.
It is alleged Mr Ullah was responsible for a blog site which allegedly contained information about IS and cyber-security guidance.
He was further charged with directing "the activities of an organisation which is concerned in the commission of acts of terrorism".
The alleged offences took place between December 1 2015 and September 22 2016.
During the short hearing at Westminster Magistrates' Court on Wednesday morning, Mr Ullah spoke only to confirm his name, date of birth and address.
Mr Ullah was arrested in the street in Cardiff on September 22 by officers from MPS Counter Terrorism Command.
District Judge John Zani remanded him in custody.
Police and Crime Commissioner for South Wales Alun Michael said there was no heightened risk in Cardiff.
