The statement was read by group spokesman, Martin McMonagle
The Irish National Liberation Army has confirmed it has disposed of its weapons.
A spokesman for the republican terror group, Martin McMonagle, made the announcement at a press conference in Belfast on Monday morning.
"We make no apology for our part in the conflict," he said.
It was also announced on Monday that two other paramilitary groups, the Official IRA and the South East Antrim UDA, have decommissioned their weapons.
Announcing the INLA move, Mr McMonagle said: "We believe conditions have now changed in such a way that other options are open to revolutionaries to pursue and ultimately achieve our objectives.
"We can also confirm that the INLA has disarmed through a joint facilitation group consisting of local, a national and an international organisation.
"This was done in a process in accordance with international standards."
"We hope that this will further enhance the primacy of politics and that it will in time unite and advance the working class struggle in Ireland."
The facilitation group included Irish trade union leaders and an academic, who worked with the Independent International Commission on Decommissioning (IICD).
The trade unionists confirmed they had witnessed the destruction of a substantial amount of weaponry.
In 1993 Mr McMonagle was sentenced to 23 years in jail for his part in an INLA plot to launch a bombing campaign in England. He was released early under the Good Friday Agreement.
A statement is also expected by General John de Chastelain, head of the international decommissioning body (IIDC).
The legislation that enables the commission to carry out its work is due to expire on Tuesday.
Irish Justice Minister Dermot Ahern said General de Chastelain had confirmed to him that over the last few days he and his colleagues had completed the decommissioning of INLA arms.
"These events are further positive developments as we look to finally close the last chapter of the conflict and ensure a peaceful future for all the people of Northern Ireland," he said.
The INLA move was also welcomed by Sinn Fein assembly member Gerry Kelly, who called for "other small militarist factions" to do the same.
"There is no support for, or appetite for, armed actions within the republican community," he said.
"The INLA has recognised this by engaging with the IICD in this action."
The INLA, whose murder victims included Tory MP Airey Neave, is believed to have disposed of its arsenal in recent weeks.
A small, ruthless group which killed more than 120 people, it announced in October that it intended to pursue its aims by exclusively peaceful means.
The republican paramilitary body is believed to have been responsible for 111 murders from its formation in 1975 until its ceasefire in 1998, but it is also thought to have been involved in a number of murders since then.
In February 2009, the INLA claimed responsibility for the murder of a drug dealer in Londonderry.
It came to world prominence in 1979 with the murder of Conservative Northern Ireland spokesman Airey Neave by leaving a bomb under his car in the House of Commons car park.
It was behind one of Northern Ireland's worst atrocities when it killed 17 people in a bomb attack on the Droppin' Well pub in Ballykelly, County Londonderry, in 1982.
The group's political wing, the Irish Republican Socialist Party held a parade in Bray, County Wicklow, four months ago where it announced that the organisation had renounced violence.
At the moment, paramilitaries moving weapons can use a certificate from the Independent International Commission on Decommissioning (IICD) saying they are moving arms from one cache to another to facilitate decommissioning.
However, after the legislation expires any weapons found can be forensically tested.
Evidence from this could be used in future court cases and possibly help secure convictions.
