ISIS hostage John Cantlie ‘believes two-thirds’ of what he says in propaganda videos, says his sister

British hostage John Cantlie believes ‘two-thirds’ of what he is saying in propaganda videos released by Islamic State, according to his sister.

The photojournalist, who was kidnapped by jihadists nearly two years ago, has been shown in a series of videos recently in which he speaks about ISIS, and criticises both the UK and U.S. governments over their strategies to deal with the terrorists.

Mr Cantlie, who wears an orange jumpsuit and appears to be reading from prepared scripts, has said it is true that he is a prisoner but claimed he had been abandoned by the government.
