Bomb disposal experts have carried out a controlled explosion on a bus in Edinburgh after a suspect package was discovered on board.
Police evacuated a section of Princes Street after the find was made.
A spokeswoman said they had cordoned off the area and added that officers were on high alert due to the terror attacks in London and the G8 summit.
