Concern is growing for more than 20 Irish people who are still unaccounted for in the wake of the disaster.

Relatives of some of those missing have begun arriving in the region.

Although diplomats in Asia have not confirmed any deaths among the Irish community, the families of two Dublin women say they are holding out little hope for their safe return.

The families of three victims who went missing in Thailand travelled to the Asian country this week to try to locate and identify their bodies.

But a spokesperson for the Department of Foreign Affairs said that the majority of the 20 people who have yet to be traced were not in the areas worst affected by the tsunamis.
