Police in Derry appeared to pull back after coming under attack as an un-notified republican parade made its way through the Creggan area.
This followed warnings from Assistant Chief Constable Bobby Singleton and other senior PSNI officers that intelligence indicated dissident republicans would attempt to use "public disorder" in the area as a "platform to launch terrorist attacks" against officers.
While a helicopter flew overhead during the event there was little other visible sign of police presence in the area beyond a number of police vehicles.
