Majority of IRA arsenal came from Libya and US

The IRA is believed to have kept secure much of its arsenal since it announced the second ceasefire in 1997, though some of it was secreted away following a split in the ranks that year.

A large percentage of the arsenal was acquired from Libya during the 1980s, though some of it was smuggled in from the United States in the '70s and early '80s.

General John de Chastelain has revealed no details of what has been put beyond use.
