General John de Chastelian has described IRA decommissioning as "an important milestone towards the completion of (the international decommissioning body's) task to achieve decommissioning by all paramilitary groups".
He said he still believed full decommissioning by all groups was possible. He said decommissioning of the weapons belonging to the IRA had to be achieved without the suggestion of surrender or defeat and those conditions remained.
He said much of his work and that of his two fellow commissioners had been carried out in secrecy and there were those who had questioned the secrecy.
He said he understood the desire of those who have been subjected to violence to see that the threat has gone, but that has not been simple.
The general and his colleagues are to retain the inventory of the weapons they have seen destroyed.
