Vehicles were set on fire during Thursday's disturbances

Six men arrested in Belfast on Thursday in connection with the loyalist feud have been released without charge.
It is understood the arrests were linked to the murder of Stephen Paul, 28, who was shot last Saturday.
Loyalist paramilitaries were blamed for rioting in the north of the city which followed Thursday's arrests, during which 40 police officers were injured.
Three people have so far been killed as a result of the feud between the LVF and the UVF.
Petrol bombs were thrown and a bus and 10 cars hijacked and set on fire in disturbances on the Crumlin Road following the men's arrests.
