An investigation is under way after shots were fired at a police patrol in West Belfast.
The incident happened at around a 11.45pm in the Suffolk Road area of the city.
The PSNI say a police Landrover was hit by two shots and that no one was injured.
The gun attack comes 24 hours after a number of shots were fired at police vehicles in north Belfast. Again officers escaped injury in that incident.
PSNI district commander for the area, Chief Superintendent George Clarke, said: "For the second night in a row, dedicated community police officers have found themselves under attack from terrorists.
A military-grade Kalashnikov weapon was used to fire the 10 shots at police vehicles.
The police cars were towing digital signs through a residential area near Ardoyne in north Belfast on Thursday night.
Two vehicles and one digital sign were hit by the bullets as they passed by what is a flashpoint inner city area which has seen serious violence in recent times linked to dissident activity and contentious loyal order marches.
Police have recovered one weapon.
The threat posed by dissident republicans remains classed as severe.
Separately, a man has died after what is believed to be a work-related accident in Lisnaskea Co Fermanagh.
The incident happened at a garage on the main street of the border town.
A PSNI spokesman said the police are investigating the death.
