Images have emerged of the counter terrorism drill in the Capital.
Images show emergency service staff taking part in a counter-terrorism exercise responding to a scenario simulating a vehicle attack held in the grounds of the Royal Bank of Scotland headquarters at Gogarburn.
Police said the “live-play scenario” is not in response to any specific threat but the result of more than a year of planning.
Scotland’s Cabinet Secretary for Justice Michael Matheson said: “Scotland has a key role to play in hosting this exercise, alongside the UK Government and other agencies.
“It provides an opportunity to test our response in Scotland and the readiness of our emergency services to deal with this kind of incident.
“The Scottish Government shares the commitment of our partners to taking all necessary steps to assess and strengthen our preparedness to deal effectively with terrorism.
“While fortunately such real life incidents are rare, the public can be assured that government, our blue-light services and other agencies are continuously testing and reviewing how we are best able to respond to an attack should it happen.”
