LONDON (AP) — The parents of a British Muslim convert who is believed to have joined the Islamic State group are set to stand trial in January for terrorism-related charges.

John Letts and Sally Lane are charged with funding terrorism for allegedly sending money to their 20-year-old son Jack Letts.

Jack Letts left his home in Oxford and travelled to Syria in 2014. He has been dubbed "Jihadi Jack" by some British media.

His parents are accused of transferring payments of roughly 1,750 pounds ($2,600) in 2015 and 2016. They were released on bail.

The trial date was set Thursday during a hearing at the Old Bailey court.
