Traffic lights out across Shantallow, Foyle Bridge - power cuts likely to last until 10am

UPDATE:  The overnight power cuts have left parts of Derry without traffic lights.

Homes in Shantallow and Galliagh are still affected by the cuts - some are out entirely, while others have light and enough low voltage electricity for lower-powered devices and lights.

Councillor Sandra Duffy has spoken to Northern Ireland Electricity and says they hope to have supplies restored by 10am this morning.

Councillor Angela Dobbins said that electricity went off around 4.30am - NIE said it was a circuit breaker fault.

Around 3,000 homes have been affected.
