The elderly couple held for nearly eight months by the Taliban have said they feared never being released – or even being executed.

Peter and Barbie Reynolds finally flew back to the UK at the weekend after intense diplomatic efforts led by Qatar.

They were detained in ten jails, including the notorious Pul-e-Charkhi where they were sometimes held in a cage or a windowless basement – but they never learned why they were arrested.

'We had begun to think that we would never be released or that we were even being held until we were executed,' Mr Reynolds, 80, said.

'The last few months, we have been together in solitary confinement, cut off from all awareness of what was going on in the world.'
