'Mow down enemies in your 4x4s'.
In a chilling call to arms, Anwar al-Awlaki ordered terrorists to stockpile weapons, then jump in trucks and mow down crowds in busy city centres.
He writes in a handbook for would-be terrorists: "The idea is to use a pick-up truck as a mowing machine, not to mow grass, but mow down the enemies of Allah."
Al-Awlaki is hiding out in Yemen. His call has echoes of the deadly commandostyle raids in Mumbai, India, two years ago, which left 166 dead and hundreds of others injured.
He recruited extremists during a spell in London.
Just two weeks ago it emerged police are being given more powerful guns and SAS-style training.
