The 100th anniversary of the sinking of the Titanic is being remembered at events across the world, including in the ship's birthplace Belfast.
A Titanic Memorial Garden - with the names of 1,512 victims etched on five bronze plaques - is being opened close to where the liner was launched.
A service is being held in Southampton where the voyage to New York began.
And at the North Atlantic site of the sinking, memorial cruise ship Balmoral is marking the time it hit an iceberg.
The ship has arrived at the site where the Titanic sank 400 services miles (460km) off the coast of Newfoundland on 15 April and passengers and crew are holding commemorations to mark the tragedy.
Another cruise ship, Azamara Journey, has sailed from New York to take part in the ceremony.
Descendants of the victims are expected at the services, and will lay wreaths and join in a minute's silence in memory of all those who died.
