A Terrorist Incident

Summary of incident

A car has struck a group of soldiers in a Paris suburb earlier today, injuring six, two seriously, according to French Police and Security sources.

French police report that a man has been shot and arrested after they intercepted the car on a motorway north of the capital. The soldiers were injured outside a barracks in the north-western suburb of Levallois-Perret on Wednesday morning (9 August 2017).

The Paris prosecutor said the attack was “attempted killings… in relation to a terrorist undertaking”. Readers will recall that France has been under a state of emergency since November 2015.

Implications for readers

This attack reinforces our concerns that vehicle ramming is likely to be a favoured tactic of terrorists for the foreseeable future. Consequently, for customer sites where Hostile Vehicle Mitigation is in place, it should be used accordingly. Security teams should maintain vigilance and continue to pay attention to vehicles being driven:

  • Erratically
  • At unusually high speeds in built up areas

All such incidents should be escalated appropriately.

For readers operating sites of an iconic status or a high-risk rating, reassessing the physical barriers and perimeter protection is essential.

Following on from this, we at Corps Relay would like to reinforce the importance of the ‘Onion Skin Principle’. In applying our ‘Eight Principles of Security’, which readers will be aware of, we also recommend building into resilience programmes the tried and tested ‘Onion Skin Principle’ of applying a robust ‘layered’ approach to security. This will (when applied properly) ensure that there is ‘defence in depth’ to deter, hamper, and slow down the efforts of even the most determined adversary, and thereby provide time for effective alerts to be raised, and for Security Officers and/or Police to be alerted, and respond accordingly.

The current threat level from international terrorism for the UK was decreased on 27 May 2017 and is now assessed as SEVERE


The threat level for Irish related terrorism is set separately for Northern Ireland and Great Britain


In Northern Ireland it is SEVERE and in Great Britain it is SUBSTANTIAL


  • CRITICAL means that a terrorist attack is imminent
  • SEVERE means that a terrorist attack is highly likely
  • SUBSTANTIAL that an attack is a strong possibility
  • MODERATE that an attack is possible but unlikely


Everyone should always remain alert to the danger of terrorism and report any suspicious activity to the police on 999 or the anti-terrorist hotline on 0800 789 321.


You may end up saving a life or lives… and there is nothing more rewarding than that…
