Shortly before the deadline set by peace process leaders, the republican splinter group the Irish National Liberation army has disarmed.

The group surrendered its weapons to the Northern Ireland disarmament commission in November and in January, representatives told the Associate Press just days before the Anglo-Irish disarmament deadline lapses.

On Monday an expert panel, formed by Britain and Ireland in 1997 to oversee disarmament of terrorist groups, will confirm the surrender of the weapons, which were handed over at secret meetings, according to the Associated Press. Legislation allowing paramilitaries to surrender weapons without punishment will expire on Tuesday.

The INLA came into being in the 1970s, following bloody in-fighting within the IRA. Smaller than the IRA it has nevertheless played a brutal part in the Northern Irish conflict. Between 1974 and 1998 the group has been responsible for the deaths of 110 people.

In 1982 the group bombed a disco favoured by British troops, killing 11 soldiers and six civilians, and wounding 30 others.

A year later the INLA machine-gunned a Protestant gospel hall during a Sunday service, killing three and wounding seven, including the organist.

Internal violence has also plagued the INLA. In 1994 fellow members of the group killed the leader, Dominic “mad dog” McGlinchey, shooting him 14 times in front of his teenage son.
