Police in north Belfast were tonight confronted by angry loyalists who hijacked cars and threw petrol bombs during tea time.
Three cars and a tip up lorry were hijacked and set on fire during disturbances in the Crumlin Road area at around 5.30pm.
There were also disturbances in Cambrai Street and Enfield Street.
Police sealed off the Crumlin Road near Tennent Street and Brookfield Mill.
It is believed the disturbances are connected to the arrest of six men during a police operation linked to the ongoing paramilitary feud between the Ulster Volunteer Force and the Loyalist Volunteer Force.
The feud has claimed the lives of three men, the most recent being Stephen Paul, who was shot dead outside a house in Wheatfield Crescent on Saturday.
All three murders have been attributed to the UVF.
