A 20-year-old man is due in court in the North today on terror charges.
He is accused of possessing weapons and ammunition for use in terrorism, criminal damage and making death threats.
Two other men, aged 43 and 18, face charges of aggravated burglary, death threats and possessing weapons.
It follows an incident last Friday morning when men forced their way into a house in Hollymount Park in Derry.
All three men will appear before court in Magherafelt later.
