New terror alert hits trains and airports amid fears of Mumbai-style attack in London
A fresh terror alert was issued yesterday amid fears of a Mumbai-style attack on airports and the London transport system.
Insiders said security officials had raised the specific threat to the transport network – meaning an attack was ‘highly likely’.
Transport police were ordered to cancel their leave so extra officers could be deployed across the Tube and busy airports, including Luton and Heathrow.
Security is likely to be ramped up, with potential extra restrictions for travellers.
It also emerged the emergency services have been briefed about how to respond to a copy of the 2008 Mumbai machine gun attacks.
The increased terror alert, confirmed in a memo sent to staff at airports and Transport for London yesterday, follows a string of warnings that Britain could face a new Al Qaeda-inspired attack.
Details of the latest alert emerged following the increase to the specific threat faced by the transport and aviation ‘sub sector’.
MI5 and the Home Office publish the nationwide level terror threat, which is currently rated ‘severe’.
But JTAC, the joint terrorism analysis centre based inside MI5, also compiles threat levels relating to individual elements of the UK’s infrastructure.
Normally, these threat levels are classified. However, it last night emerged that – in relation to airports and the London transport system – the threat level had been raised to state that an attack is now considered highly likely.
It points to intelligence being received about a specific threat. Whitehall sources said the rail travel alert related to London rather than stations nationwide.
British Transport Police would not comment on the deployment of extra officers yesterday.
A spokesman for the Metropolitan Police said: ‘The threat level to the UK is at severe, which means that an attack is highly likely, and has been since January 2010. We will police accordingly and use a range of covert and overt tactics which remain under constant review.
‘We continue to encourage the public to remain vigilant and aware and to trust their instincts and report any suspicious behaviour which may be terrorist-related.’
