Dublin feud: Timeline of 'gangland' murders
A violent feud between two rival Irish gangs is believed to have claimed the lives of several men, including a dissident republican from Northern Ireland.
BBC News looks at the gun attacks thought to be linked to the dispute between some members of the Kinahan and Hutch families, which has caused fear in Dublin and further afield.
September 2015 - Gary Hutch murder
Gary Hutch, a convicted armed robber from Dublin, dies after being shot by a masked gunman at an apartment block in Spain's Costa del Sol.
The 34-year-old had moved to Spain after his release from an Irish prison and had been living in the country for eight years at the time of his death.
He had survived a number of previous attempts on his life.
He was a nephew of Gerry Hutch, a notorious criminal in Dublin in the late 1980s and 1990s, who was nicknamed the Monk.
30 December 2015 - Darren Kearns murder (Suspected connection)
Convicted drug dealer Darren Kearns is shot leaving a Chinese restaurant on Blackhorse Avenue with his wife.
Garda believe the murder is linked to organised crime but do not initially link it to Hutch's murder.
Links to the gang feud are only investigated after the later Regency hotel incident.
5 February 2016 - David Byrne murder
There is chaos and panic as gunmen armed with AK47 assault rifles open fire inside a Dublin hotel as it hosts a weigh-in for a World Boxing Organization title fight.
The armed gang, disguised as police officers, injure three men, one of them fatally.
The murder victim is named as 33-year-old David Byrne, from Crumlin in the south of the city.
He was well known to police and had been questioned several times over serious and organised crime.
Police sources express fear of the possibility of a reprisal attack.
Irish police are routinely unarmed, but in the wake of the gun attack armed officers man check-points in a bid to prevent any retaliation.
8 February 2016 - Eddie Hutch Sr murder
A man claiming to speak on behalf of the dissident republican group the Continuity IRA (CIRA) claims its members were responsible for the hotel gun attack.
He tells the BBC that CIRA members killed Mr Byrne because he had been involved in the killing of Real IRA leader Alan Ryan in Dublin in 2012.
However, police say they believe the motive for the hotel shooting was a criminal dispute, not a paramilitary feud.
Hours later, Eddie Hutch Sr is shot dead near his flat on Poplar Row in the north inner city, in a suspected reprisal attack for Mr Byrne's murder.
The victim, a taxi driver, is an uncle of Gary Hutch and a brother of Gerry 'The Monk' Hutch.
At his funeral, mourners hear a plea from the Hutch family for no retaliation.
Locals believe Eddie Hutch Sr was only murdered because of his surname, and that he was an innocent man whose early life in crime was well behind him.
