Thirty firefighters and three US airforce water carriers were called to a large fire in an ammunition store this morning (Saturday).

The blaze at Lakenheath Clay Target Centre in Eriswell, broke out at 6.40am in a building containing ammunition used for clay pigeon shooting, and which also housed a shop and bar.

Fire crews from Brandon, Mildenhall, Bury St Edmunds, Thetford and Newmarket and three water bowsers (a water tank truck) from a nearby airbase attended the fire.

The blaze affected up to half of the building, which measured 80 by 40 metres. Crews brought it under control by 10.40am.

The cause is not yet known but a fire investigation officer was due to visit the site this afternoon.
