A British terror suspect linked to the main mastermind of the 2013 Westgate Mall attack, Jermaine Grant, will remain in prison after his bid for release was rejected.

Grant, who has been in custody over terrorism-related charges, had moved to be freed but failed to convince the court, which opted to extend his incarceration.

Grant - accused of being an associate of terror mastermind Samantha Lewthwaite - has been in a UK prison since August, when he was deported from Kenya, and has spent 13 years behind bars for terror offences in Africa.

He was recalled to prison for breaching licence conditions over a 1999 rape conviction and was automatically put up for parole last month, but his release was denied, according to the Mirror.
