Northeast Syria is rapidly changing hands, and with it the country's fragile balance of power.

The last time there was a power vacuum in the country, ISIS was born.

Around 7,000 Islamic State group detainees held in prisons in Syria are being transferred to Iraq in an operation overseen by the US.

But will the instability in the region affect that transfer and allow the organisation to regroup?

Niall's joined by Sky's international correspondent Alex Rossi who has seen first-hand the conditions in those camps.

Half of us will develop cancer at some point in our lives, according to Cancer Research UK. And the speed of a diagnosis can often be the difference between life and death.

Just a one-month delay can raise the risk of death by up to 10%. Yet in England, almost a third of cancer patients wait more than two months to start treatment after an urgent GP referral - twice as many as the target and a trend that’s getting worse.

Niall speaks to Sky’s health correspondent Ashish Joshi and Jesper Fisker from the Danish Cancer Society.
