BREAKING: Continuity IRA claim responsibility for Regency Hotel attack
The Continuity IRA has claimed responsibility for the military style attack on members of the Kinahan crime syndicate.
In a statement to the BBC a man claiming to speak on behalf of the leadership of the Continuity IRA said its members were responsible for the shooting,
The spokesman claimed that the attack was carried out in revenge for the 2012 murder of RIRA chief Alan Ryan.
The spokesman said David Byrne was targeted for his involvement in the killing.
"Although not a member of our organisation, we are not going to stand back and allow drug dealers and criminals to target republicans," the CIRA spokesman said.
He claimed that this would not be "an isolated incident", warning that further attacks were planned.
"This will not be an isolated incident," he said.
"Continuity IRA units have been authorised to carry out further operations. More drug dealers and criminals will be targeted.
"The Continuity IRA will carry out further military operations."
However gardai still believed there is a gangland angle to the shooting as the veracity of these claims is unproven, and that the Byrnes and Kinahans are not suspected by officers to have been involved in Alan Ryan's murder
Criminal David Byrne was shot dead and two others were injured as two gunmen armed with AK-47s - and two others with handguns - opened fire in the Regency Hotel in Dublin.
Three of the men were dressed in SWAT team uniforms, the other was disguised as a woman.
The brazen shooting occurred as about 100 people, including several members of the Christy Kinahan crime syndicate, attended a weigh-in for a boxing event.
Two men with AK-47s began firing shots as they reached the main front door of the hotel.
Sean McGovern (30), from Captain's Road in Crumlin and Aaron Bolger (25), from Killinarden in Tallaght, were injured in the attack.
