British army bomb-disposal experts have been called in after a fatal blast at a mansion on the Channel Island of Guernsey.
Police say a middle-aged man died Friday in an apparent explosion at the home in an affluent part of the quiet island, which has a population of about 65,000.
The Guernsey Police force says "quantities of an explosive substance" were later found at the house.
Police says there is no evidence linking the incident to terrorism, and no risk to the public.
A post-mortem is due to take place Monday on the dead man, who has not been formally identified.
Guernsey is one of the Channel Islands, British Crown dependencies located in the English Channel west of France's Normandy peninsula.
