Three Fire crews have been scrambled to the Wellington Barracks. Crews were called just after 11pm on Tuesday evening.
The military barracks is in Westminster, central London, and houses the Foot Guards battalions on public duties in that area. The building is located about three hundred yards from Buckingham Palace, allowing the guard to be able to reach the palace very quickly in an emergency. It lies between Birdcage Walk and Petty France. Three companies are based at the barracks, as well as all of the Foot Guards bands and the regimental headquarters.
