The fog horn on the Hanois Lighthouse off the British Island of Guernsey has been silenced after sounding continuously for two weeks, despite there being little or no fog.

Peter Gill, Guernsey's harbour master, said the fog horn was turned off after the problem came to light on Tuesday.

Trinity House, which looks after a lot of Britain's lighthouses, said an automatic sensor had failed and they were now operating the signal manually.

Engineers are expected to travel to the lighthouse on Monday to make repairs.
