Three men have been charged with preparatory acts of terrorism by detectives investigating the attempted murder of Detective Chief Inspector John Caldwell.
The men are aged 45, 47 and 58.
The 45-year-old man and 58-year-old man have been further charged with possession of articles for use in terrorism, and providing property for the purposes of terrorism.
All three are expected to appear before Belfast Magistrates’ Court on Wednesday.
All charges will be reviewed by the Public Prosecution Service.
