Three ISIS fanatics have been arrested in Pakistan over fears they were planning a terror attack no British soil on the 10th anniversary of the July 7 bombings.

Maps of London and ISIS propaganda were found on their computers during a police raid on a shop in Peshawar, north-west Pakistan.

Documents threatening Pakistan's army were also seized but no weapons were discovered.

Pakistani news websites have named them as Asmatullah and Abdur Rehman - two Afghan nationals - as well as Mohammad Ibrahim.

Security checks on international flights out of Pakistan have been tightened to prevent terrorists wreaking havoc in the UK next week, ten years after a series of explosions killed 52 in London, sources told the Mirror.

A spokesman for Pakistan's interior ministry said checks had been intensified, adding: 'The aim is to secure airports.'

A senior officer of Peshawar police told MailOnline: 'It was a joint operation by military intelligence and local police over a tip-off that certain elements are involved in anti state activities.

Mohammad Saeed added: 'When we raided the Urmur area of Peshawar, three persons were arrested along with ISIS pamphlets and other Jihadi literature.

'A desktop was also recovered which had different jihadi videos of Daesh [ISIS].'

The suspects were interrogated for a few days before the police charged them with conspiracy against state and hate speech and literature before sending them to prison.

The terror group poses a 'huge and deadly threat' to the UK, a former Scotland Yard chief told the Mirror.

Peter Clarke said: 'At the moment we are arresting one person for terror-related crimes every day. That's the highest rate at any point in 15 years, apart from the immediate aftermath of 9/11 and 7/7. There are 120 people awaiting trial as we speak.'

But he added that 'massive plots to commit terrorist acts have been thwarted' every year since the July 7 bombings and hailed UK's counter-terrorism 'the envy of the world'.
