A 44-year-old man is to appear in court today charged with the murders of two soldiers and the attempted murder of six other people at a military base in Northern Ireland.
Sappers Mark Quinsey, 23, from Birmingham, and Patrick Azimkar, 21, from London, were shot dead at Massereene Army barracks in March as they waited for a pizza delivery at the gates of the Antrim base.
The man, also charged with possession of a firearm and ammunition with intent to endanger life, was arrested in mid-Ulster on Tuesday.
He is to appear in court today in Ballymena, Co Antrim.
One man has already been charged with the attack which took place on 7 March.
Gunmen from the dissident republican Real IRA opened fire on the soldiers outside the barracks as they collected pizzas.
Those injured in the attack included pizza delivery men.
