The solicitor representing families of victims of the 1981 Stardust fire has said considerable progress has been made on plans to try to identify the remains of the five unidentified victims of the fire.

Greg O'Neill said it was his belief that it was certainly an issue that the families will be able to advance.

He said the DNA technology required was not available in this country but that he believed the families' legal team are now in a position to put in place a process into which government can connect to allow identification to commence.

Relatives and friends of victims of the tragedy attended a special Mass in Dublin this afternoon.

The Mass was held to remember in particular the five victims of the fire whose bodies were never formally identified.

At the Mass relatives and family members spoke emotionally about their loved ones and prayers were offered for all those who died and for those who were injured and their families.

Following the Mass at St Fintan's Church in Sutton, the relatives travelled the short distance up the road to the nearby cemetery where the remains of the five unidentified victims are buried.

At the grave wreaths were laid in memory of the five.

The Mass was also attended by local TDs Finian McGrath, Michael Woods and Sean Haughey, while the Taoiseach was represented by his aide de camp, Commandant Micheal Murray.

48 people died in the disaster, which happened in February of 1981.
