The parents of a British Muslim convert, believed to have travelled to Syria to join Islamic State of Iraq and the Levant in Syria, have been remanded in custody after facing terrorism charges at court.

John Letts, 55, and his wife Sally Lane, 54, from Oxford, denied sending him £1,700 knowing it would be used for terrorism.

They appeared at Westminster Magistrates' Court on Thursday morning charged with a series of terrorism offences.

They are both accused of three counts of arranging the availability of property or money to another person knowing or having reasonable cause to suspect it could be used for the purpose of terrorism.

Their son Jack Letts, dubbed "Jihadi Jack", was suspected of being the first white Briton to join the terror group after he left his Oxford home and travelled to the war-ravaged country last year.

The 20-year-old reportedly goes by the name Abu Mohammed and married an Iraqi woman with whom he has a son, Muhammed.
