Turkey has warned that it will send British Islamic State members back to the UK if they come into the custody of Turkish forces in Syria.

Suleyman Soylu, the Turkish interior minister, told Britain and other European governments that Turkey was “not a hotel” for foreign jihadists and vowed to send them home.

“When there is a Daesh member, they cancel his or her citizenship, making the person stateless. Then, they take no responsibility,” Mr Soylu said. "That is not acceptable to us. It's also irresponsible.”

Tooba Gondal, 25, is the only British Isil member so far known to have ended up in Turkish custody. She and her children escaped from a Kurdish-run facility in northern Syria last month and ended up in the hands of Turkish-backed Syrian rebels.

Ms Gondal was known as “the Isil matchmaker” because she used her social media accounts to try to convince other young British women to follow in her footsteps and become wives to jihadists.

Britain has for years resisted pressure from the Kurdish-led Syrian Democratic Forces (SDF) to take back Isil members from the UK.
