A father and two sons have died following a shooting incident at a farm in Co Cork.
It happened at a farmhouse outside Kanturk in the north of the county.
The body of one of the sons was found in a bedroom of the house. The bodies of his brother and father were found in a field up to half a kilometre away.
The men have been named as 59-year-old Tadg O'Sullivan and his sons Diarmuid, 23, and Mark, 26.
All three men had gunshot wounds.
Two rifles and a shotgun were found at the scene.
It is understood the incident is being treated by gardaí as a murder suicide.
The Garda Technical Bureau and the Assistant State Pathologist, Dr Margot Bolster, have carried out a preliminary investigation.
The alarm was raised at around 7am when a woman in her 60s arrived at a neighbour's house in a distraught condition, saying there had been a shooting at the family home.
Local gardaí and the emergency services went to the farmhouse at Assolas, on the outskirts of Kanturk in north Cork and called for backup.
Members of the Armed Response Unit from the southern region were among the first to respond.
Two cordons were put in place - one around the isolated farmhouse and a second on roads leading to and from the townland - as per protocols in incidents such as this.
They were later joined by an unit from the Emergency Response Unit from Dublin who arrived at the townland in a Air Corps helicopter.
Garda negotiators were also at the scene in case they were needed.
A medical intervention team from the HSE, which included two doctors and two paramedics, were also airlifted to the scene by the Irish Coastguard helicopter based in Dublin, Rescue 116.
An assessment was made of the house and a decision was made to enter just before 12.30pm.
The scene has been sealed off.
A family liaison officer has been appointed and an incident room has been established at Kanturk Garda Station.
Gardaí say they are not looking for anyone else in connection with the incident at this time.
