The Irish woman who died in a terrorist attack in Tunisia has been named locally as Lorna Carty.
Ms Carty, from Meath, is one of 37 people to have lost their lives after two gunmen armed with assault rifles opened fire on holiday makers at a beach beside two hotels in Sousse.
British, German and Belgian tourists are also among the dead. The mother of two was a member of Dunderry GAA Club.
Its secretary Billy Bligh says the community is in shock:
Earlier Minister for foreign Affairs said he was "not in a position to exclude the possibility of there being further Irish fatalities" in the attack, and that a number of Irish families were in the immediate vicinity.
Meanwhile the Department of Foreign Affairs has raised its security status for Irish citizens intending to travel to Tunisia.
Associated Press reports that Tunisia's Minister for Health has said 37 people are dead and 36 wounded.
Tourists fled from the beach in Sousse to take refuge in hotel rooms after guns were fired on the beach.
Tunisia's Health Ministry has said British, German and Belgian nationals are also among the dead.
One man said his son saw someone get shot as he raced back to the hotel from the sea.
Photographs seen show one man in his 60s or 70s lying in a pool of blood in his swimming shorts.
The country's interior ministry says one gunman has been killed, while there are reports that the second gunman has been captured by police.
Local radio reports say British and German tourists make up most of the casualties.
Tourists are now gathered in hotel reception areas and hiding in rooms as the situation develops.
British tourist Gary Pine said: "We thought fire crackers were going off but you could see quite quickly what was going on. There was a mass exodus off the beach. My son was in the sea at the time and myself and my wife were shouting at him to get out and as he ran up he said I’ve just saw someone get shot."
Holidaymaker Susan Ricketts said: "It sounded like a machine gun going off. There are people crying and going hysterical. We just came up to our room."
There are reports that a tourist flight from Brussels to Tunisia has been turned around.
The Department of Foreign Affairs has opened a consular support line following the incident.
The Irish embassy in Madrid and Honorary Consul, in conjunction with EU embassies in Tunis, are monitoring the situation.
"Given the number of Irish holiday makers in Tunisia we have opened a dedicated consular support line as a precautionary measure," the department says in a statement.
Anyone with concerns about this incident should call the department on 01-418-0200.
Irish citizens in Sousse are advised to follow the instructions of the police, tour operators, and their hotel staff.

She outlines what she has been hearing about the attacks.

Meanwhile Spain has raised its terror threat level to the second highest as a precautionary measure following the attacks.
