According to Mirror.co.uk, a new terror-training manual told extremists to pretend to be gay if a woman approaches them in case she is a "honeytrap" spy sent by security services.
"Many hotels - especially in busy UK cities - have women hanging around the lobby areas in order to attract men," said the manual. "A young beautiful woman may come and talk to you. The first thing you do to protect yourself from such a situation is to make prayers for steadfastness," it said.
"The second thing is to find an excuse to get away from her that is realistic and sensible, such as you having a girlfriend for the past few years and you are loyal to her or you are homosexual," it added.
The 64-page guide in English was written to try to stop the police and MI5 from uncovering the identity of terrorists plotting attacks on British soil, the report said.
It was produced by Taliban warlords in Afghanistan and was discovered by Mirror investigators on a militant website used by UK cells.
It has emerged just months after MI5 launched a recruitment drive for women to work as spies.
The guide was placed online after Osama bin Laden was killed, suggesting al Qaeda and Taliban leaders are determined to launch revenge attacks on the UK.
