HALIFAX -- A navy warship whose hull was damaged while being towed from Ontario to Halifax has resumed its journey to its home port.

The Department of National Defence says the HMCS Athabaskan left North Sydney around 8:30 a.m. Sunday and will arrive in Halifax in two or three days.

The military says tethering lines broke as the destroyer was being towed in rough waters off a rocky shoal near Cape Breton.

It had said minor, temporary repairs were made on the 40-year-old vessel to ensure its hull is watertight during the towing process.

The military says once the HMCS Athabaskan arrives in Halifax, officials will conduct a thorough assessment on the ship's condition.

The vessel had just undergone a $26.7 million refit in St. Catharines, Ont.
