Anti-terrorist police arrested four men in London in early morning raids today.
The arrests followed searches at two addresses in Barnet, north London, and one in nearby Finchley.
Two of the men were arrested in a vehicle in Barnet, police added. All are being held at a central London police station.
Britain has arrested more than 700 people under anti-terrorism laws since the September 11th, 2001, attacks on the United States.
Of these, around 120 have been charged with terrorism offences, and another 135 charged under other legislation.
