A Russian student who made the terrorists' "explosive of choice" and boasted on social networks of using peroxide to "whiten n******" has been jailed for two years.

Vladmir Aust, 19, created volatile HMTD using simple ingredients he bought for £22 from Amazon and stored it in the bedroom of the seven-storey halls of residence where he lived in Newcastle.

Referring to Aust's racist language, Mr Justice Coulson, sentencing at Newcastle Crown Court, said the words he used on the Russian equivalent of Facebook, known as VK, "spoke eloquently of his unsophisticated world view".

But he said there was no evidence of him having links to any dangerous political group, or evidence of him intending to attack any group.

The halls, which are home to 112 students, had to be evacuated in June and disruption was caused to the city centre.
