The arrests were made by Scottish police, who led the operation, along with officers from the PSNI and the Security Service.
Assistant Chief Constable Ruaraidh Nicolson said the arrests were made at "several locations" under section 41 of the Terrorism Act 2000.
It is believed they are being held in Govan police station in Glasgow.
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."
