Secret documents revealing scores of ISIS terror plots targeting the UK and Europe have been seized in Iraq and Syria.
Intelligence showed chilling plans by militants to kill and maim civilians, the Daily Mail reports.
Britain's top commander in the region Major General Rupert Jones said tens of thousands of documents in ISIS's 'external operations hubs' had been uncovered as towns were liberated from the terror group.
In a bid to process the mass of data, hundreds of analysts are being flown to a top secret location to wade through papers, hard drives and mobile phones.
Experts are also waiting to decipher what they believe will be a 'labyrinth of intelligence' when coalition forces retake the Iraqi city of Mosul.
