These are the shocking images a Welsh teenager who planned a terror attack on Cardiff created.

The teen, from Rhondda Cynon Taf, has been convicted of planning to drive a car into a crowd of people in Cardiff.

Targets he researched included Cardiff Castle, the New Theatre, the Capitol shopping centre, Central Library and a Justin Bieber concert that took place in the city on June 30 this year.

The A-Level student, who cannot be named for legal reasons, will be sentenced early next year but the Crown Prosecution Service (CPS) has now issued the images he created.

One included an image of Cardiff Castle with the words 'Cardiff are you prepared' and images of the Isis flag, a dagger, a Jeep and a bomb emoji.

A second image was of a suicide bomb belt with the word 'Cardiff' added.

They were found on his Instagram account, which had the password 'Truck Attack'.

His internet history included searches for: 'ISIS beheading video', 'Isis terrorist attacks', 'Police car UK armed response', 'how to create a terror attack', 'driving a lorry into a crowd of people' and 'what does getting shot feel like'.

He also researched the murder of Fusilier Lee Rigby and information on how to steal a car.

His mobile phone contained images of the truck attacks in Nice and Berlin.

The CPS also released pictures of a rucksack, and a hammer and knife that were found inside it.

Police found the rucksack in the 17-year-old's bedroom which contained the large knife, hammer and a so-called 'martyrdom letter'.

In the letter he declared that he was "a soldier of the Islamic State and I have attacked Cardiff today".

He went on to detail his plan to run down people and then attack emergency services personnel when they arrived.

Sue Hemming from the CPS said: "This teenager's behaviour over many months leaves no doubt that he intended to kill and maim as many people as possible in an attack reminiscent of the incident on Westminster Bridge.

"He was also posting extremist content online that could have encouraged others to commit terrorist acts and downloading instructions on how to carry out 'lone wolf' attacks.

"The CPS presented overwhelming evidence that he was prepared to die for Daesh's extremist world view and he will now rightly face the prospect of a substantial prison sentence."
