The Brit is accused of being a part of the so-called Islamic State.
A Briton who claims to be a pharmacist from Birmingham has been detained in Syria on suspicion of being a member of the so-called Islamic State.
The man, who says his name is Anwar Miah, is said to have been arrested by Kurdish forces a month ago near Hajin in Deir ez-Zur, a province on the Iraq border.
Footage, reportedly showing him being questioned by his captors, has now emerged on social media.
In the clip a blindfolded balding man with a British accent said his name is Anwar Miah, from Birmingham, and explained that he has been in the country for "just under four years".
Asked if he is a member of IS, he replied: "I'm a doctor. I'm a qualified pharmacist from the UK. I studied medicine and pharmacy."
"I came here to work with the general people and to work in their general hospitals.
"I've been working in the hospitals since I came."
Asked again if he was with IS, or Daesh, he said: "The areas that I worked in were controlled by Daesh, but I work with the general people I work in the general hospitals.
"I mean I don't... I mean they were controlled by Daesh, I can't do anything about that. All my work was with the public."
His detention comes after two Britons, suspected of being members of an IS execution group dubbed 'The Beatles', were captured in Syria in February.
Alexanda Kotey and El Shafee Elsheikh were captured by Kurdish militia fighters in January.
Along with Mohammed Emwazi - the killer nicknamed Jihadi John - and Aine Davis, they are thought to have been part of a group named after the '60s band because of their English accents.
The four Londoners were linked to a string of hostage murders in Iraq and Syria during the Islamist uprising.
Shiraz Maher, director of Kings College London's International Centre for the Study of Radicalisation, tweeted: "One of the big questions and dilemmas for security agencies, after Islamic State lost Raqqah and Mosul, is: who died? Who survived? How many got away and where are they now?"
"Although we see Anwar Miah in the video saying he’s a pharmacist/doctor, and even if that was his primary role within the group, it’s also extremely likely he was a fighter too."
Since 2014, Royal Air Force aircrew based at RAF Akrotiri in Cyprus have been flying daily missions over Iraq and Syria as part of a coalition of nations fighting IS.
The Operation began as a humanitarian aid mission but has grown into a complicated mission to try and defeat IS.
Earlier this month, a British General said IS is "very close" to being "tactically defeated" but warns the UK must remain "committed" and learn from previous mistakes.
