Flynn made the claims in the German newspaper Bild, where his book on winning the war against radical Islam is being serialised.

The veteran, who is a potential running mate for Donald Trump in the US election later this year, wrote: 'We looked a ruthless enemy in the eye - women and children, girls and boys, raped and exploited, the beheadings stored on a laptop next to pornography.

'At one point we actually had determined that the material on the laptops was up to 80 per cent pornography.

'These sick, psychopathic enemies were not only unimaginably hideous, but also treacherous and torn. We had to work faster to outwit them if we wanted to beat them.'

However, it is not the first time that jihadis have been linked to having pornography on their laptops.

Last year, former London mayor Boris Johnson said that homegrown fanatics from the UK who go to join ISIS are w*****s who watch porn because they can't find girlfriends.

He explained that British terrorists often become radicalised because of their badly adjusted relations with women and turn to extremism to stop them feeling like losers.

Speaking at the time, Mr Johnson said: 'If you look at all the psychological profiling about bombers, they typically will look at porn. They are literally w*****s'.

Meanwhile US officials also revealed in 2011 that former al Qaeda leader Osama bin Laden had a stash of pornography as he hid in his squalid lair in Pakistan.

U.S. Navy Seals said they uncovered the x-rated films during the mission to kill the terror leader, who masterminded the 9/11 attacks.

According to officials, the commandos found a 'fairly extensive' collection of modern porn films as they searched the building after Bin Laden was shot.
