YELLOWKNIFE - Residents in southern Northwest Territories experienced a phone and internet service outage on Saturday.

A statement from telecommunications company Northwestel says its customers in Yellowknife and surrounding communities should be prepared to be without service for most of the day.

Northwestel says cellular service, internet, long-distance phone and TV services have been impacted by damage to fibre infrastructure leading into Yellowknife.

The company did not say how many customers are affected by the outage.

Northwestel says technicians have been sent to repair the damage.

RCMP are asking residents to call their local police detachment in case of an emergency or go to a police station in person.
