A number of individuals have been arrested on suspicion of committing various offences in relation to dissident republicanism, according to Police Scotland.
Assistant Chief Constable Ruaraidh Nicolson said the arrests were made at "several locations" under section 41 of the Terrorism Act 2000.
A statement from Police Scotland said: "The policing operation, which also involved the Police Service of Northern Ireland and the security service, has been focused on the activities of individuals sympathetic to dissident republicanism but who are not affiliated to any specific group.
"Police Scotland has led the operation which has involved a number of officers, including specialist units, and public safety has been a priority throughout. We are confident as a result of these arrests there is no risk to the public.
"It would be inappropriate to comment further at this stage."
