Staff at MI5 will today join the country in two minutes of silence at 11am to mark Armistice Day and remember the sacrifice of those who have lost their lives to protect the country.
MI5 Director General Andrew Parker said:
"Today's Armistice Day - in the centenary of the outbreak of the First World War - allows us to reflect quietly on the price which is often paid to protect our national security.
"As British troops leave Afghanistan after 13 years, MI5 pays particular tribute to all those who served, especially those who lost their lives or suffered injury, in the service of their country. We will remember the tenacity, bravery and sacrifice of the 453 British Servicemen and women who died to keep this country safe. We owe them a debt of gratitude."
