A special centenary commemoration unveiling a new memorial to all the Titanic victims has begun in the "proud" city of Belfast.

The vessel, which sunk on April 15 1912 with the loss of 1,500 lives, was built in the city's Harland and Wolff shipyard. For the first time all are named on one memorial, including musicians and crew.

Thousands attended or listened to the service at the city hall.

Una Reilly, head of the Belfast Titanic Society, said: "The focus of the world is on Belfast and we are doing her proud."

She added that shock had stunned local people into silence for many years but now they had found their collective voice.

"We are all proud of this ship. What happened was a disaster, she was not," she said.

Singer Brian Kennedy and the stage's Dan Gordon were among those who appeared during the open air event.
