Electricity supplies across the islands of both Guernsey and Jersey were hit by a major power cut, which lasted only a few seconds, at 1912 BST on Thursday.

Guernsey Electricity said it believed the outage was caused by a voltage fault via the cable link with France which supplied power to both islands.

It added the details of the exact cause were still unclear.

Guernsey and Jersey Electricity are working with colleagues in France to find out why the fault occurred.

Computers, telephones and electronic equipment across the islands went dead during the outage.
