The couple have been running training projects in Afghanistan for nearly two decades. Their daughter, Sarah Entwistle, told the BBC she had not received any information about her parents in more than fortnight.

Returning to home in Bamiyan, Peter Reynolds, 79, and his wife Barbie, 75, were arrested by the Taliban on February 1.

The cause of the arrest of the couple is not known yet. Despite Taliban’s ban on women working and girls older than 12 years for receiving education, the couple was running a project including training mothers and children with the permission of local authorities.

The couple, who originally met at the University of Bath, married in Kabul in 1970. After Taliban ascension to power in 2021, Mr and Mrs Reynolds decided to stay in Bamiyan where they had been running projects since 2009.

Initially, after their arrest, the couple were in touch with their four children by text message. The family were assured by interior ministry that they were "fine."

However, three days later, the texts stopped. Entwistle, who lives in Daventry, Northamptonshire, said "It has been over two weeks since the messages stopped, and they were taken into custody. We would like the Taliban to release them to go back to their home and continue their work."

She further stated that her father is a patient and has suffered stroke, he needs his heart medication.

Details reveal that the couple were arrested alongside their American friend Faye Hall and a translator from their business.

On the other hand, The Foreign Office is cognizant with the arrest of two British nationals in Afghanistan. Yet assistance from Foreign Office is limited as the UK does not recognise the Taliban and has no embassy in Kabul.

According to the Taliban official sources, the British couple were arrested, who they believed were working for a non-governmental organisation (NGO) in Bamiyan province.

An official claimed they had been arrested after using a plane without informing Bamiyan police headquarters or the border security forces.
