Two men have appeared for a brief pre-trial hearing at the Old Bailey in connection with bomb attacks in London and Birmingham. These attacks were linked to the Real IRA.
Thirty-three-year-old James McCormack has been charged with causing three explosions, while 25-year-old Aiden Hulme is accused of conspiring to cause an explosion. The two were remanded in custody until the next court hearing on 20 May.
Two other men are still being held in connection with the same offences. Mr Hulme's 22-year-old brother, Robert, and 32-year-old Noel Maguire were both arrested and charged last year.
Police forensic experts and anti-terrorist officers are still searching the farm in Yorkshire where guns and bomb making equipment were found.
