Police were attacked for a third night, with frontline officers reportedly coming under gunfire, as fresh loyalist violence erupted in Northern Ireland over the flying of the Union Flag.

A 38-year-old man was arrested on Saturday on suspicion of attempted murder, while two others were also detained amid ongoing street disturbances.

On Saturday night officers in east Belfast came under sustained attack from a mob of around 100 loyalists throwing petrol bombs, fireworks, bricks and other masonry, the PSNI said.

A spokesman said officers dealt with disorder in the Newtownards Road, Albertbridge Road and Castlereagh Street and Templemore Avenue areas of the city, using water cannon and firing three AEP rounds (rubber and plastic rounds).

One officer was injured and a number of arrests were made, the PSNI said.
