TURKEY was accused of masterminding the massive Isis attack on a prison in northern Syria today as Kurdish-led forces regained control after days of intense fighting.

More than 500 prisoners from Ghwayran jail in Hasakah province have surrendered to the Kurdish-led Syrian Democratic Forces (SDF).

But sporadic fighting continued in the northern part of the complex, which holds more than 3,000 Isis fighters captured on the battlefields of the area known by Kurds as Rojava.
