Five people have been arrested and charged with alleged terrorism offences and conspiracy to murder.
Four men, aged 26, 30, 34 and 39, and a woman aged-27 were arrested at several locations last Wednesday.
The operation was led by Scottish and involving the Police Service of Northern Ireland and the security service.
They have been charged under a Scottish terrorism Act, which covers the preparation of terrorist acts, and alleged conspiracy to murder, a Police Scotland spokeswoman said.
After the arrests last week, Police Scotland said the operation focused on the "activities of individuals sympathetic to dissident Republicanism but who are not affiliated to any specific group".
The five people have been held at the Scottish Terrorist Detention Centre in Govan, Glasgow.
Last Friday, two days after the arrests, police were granted an extended detention period under the Terrorism Act.
The four men and one woman have now been charged and are due to appear at Glasgow Sheriff Court tomorrow.
