SAS troops deployed in London, amid terror fears

Around 50 highly-trained troops are in London as intelligence chiefs told British Prime Minister David Cameron that there had been no warning Paris would be attacked, the UK paper the Daily Star reports.

The elite Special Air Services regiment is based at a secret location on the outskirts of London and is on high alert ready to respond to any attack, the paper reports.

Former head of counter intelligence at the Cabinet Office Richard Kemp says, “Uppermost in the minds of intelligence chiefs today is the prospect of both coordinated attacks and inspired attacks.”

The SAS has not been deployed in London since the 7/7 attacks in 2005. Fifty-two people were killed in the July 7 attacks.
