British Isis fighters in Syria 'may be freed if US allows Turkey invasion'

Policy reversal by Trump raises fears captured militants could escape and return to the UK

British Isis fighters held in north-east Syria could end up being released if the US allows Turkey to invade the territory, UK politicians and the parent of one detainee have warned.

A cross-party group of MPs and peers who visited the region last month warned that Donald Trump's unexpected Sunday night decision to give Turkey a free hand "risks global security" because it could allow Isis members to escape and regroup.
