Families whose loved ones were abducted, murdered and secretly buried during the Troubles, have held a wreath laying ceremony for five remaining victims who still have not been found.
Members of Families of the Disappeared walked to Stormont's Parliament Buildings to lay the wreath.
The wreath is black and contains five white lilies, representing those who remain unfound.
Four of the victims were abducted by the IRA. One, Lisa Dorrian, was disappeared by people with links to loyalism after a party in 2005.

Those taken away, shot and buried by the IRA include Joe Lynskey, Columba McVeigh, Séamus Maguire and Robert Nairac.
A dig for Robert Nairac, a British undercover soldier who was abducted outside a south Armagh pub in 1977, concluded in Co Louth last month without success.
A small area at Faughart, just over the border had been the focus of the search.
There have been a series of digs at Bragan Bog in Co Monaghan for Columba McVeigh, who was 19 years old when he was abducted and murdered in 1975.
Sandra Peake of the WAVE Trauma Centre, which supports the families, said it was particularly difficult for those who had been offered the hope that a formal search brings.
She said: "Only the families who have experienced it know the emotional turmoil of hoping against hope that they will get that call to tell them their loved one's remains have been found - only to to be told that it was not this time.
"The unbreakable bond of solidarity with the other Families of the Disappeared is immensely important and that is why events like the Silent Walk, where they can come together in mutual support is so significant.
"Until all the Disappeared are home, the families will not rest nor will they be silent."
Searches are carried out by the Independent Commission for the Location of Victims' Remains (ICLVR) - which offers anonymity in return for information about where the Disappeared may be buried.
Lisa Dorrian was abducted in 2005 and is outside the remit of the ICLVR which can only deal with cases pre-dating the 1998 signing of the Good Friday Agreement.
However, the WAVE Trauma Centre includes Lisa as one of the Disappeared.
