Officers also had to draw batons in angry confrontations with a crowd made up mainly of youths in the Kilwilkie estate in Lurgan, County Armagh, on Monday.

Tensions in the area have been running high as republicans seek to commemorate the centenary of the 1916 Easter Rising.

Elsewhere in Lurgan, there had been concerns of trouble around an Easter Monday parade by the Apprentice Boys of Derry Protestant loyal order, but that event passed off without incident.

In Kilwilkie petrol bombs were thrown at police and a van was hijacked and set on fire.

Burning bins were placed on the railway line later in the day.

Two officers were injured in the latest incidents but their conditions are not believed to be serious, UTV reports.

Two 15-year-old boys have been arrested for a range of offences including riotous behaviour and criminal damage.

Ulster Unionist councillor Colin McCusker condemned those behind the trouble.

“Once again Lurgan’s name has been dragged through the mud by republican thugs,” he said.

On Saturday, masked men marched through Kilwilkie, a staunchly republican neighbourhood, to mark the centenary of the Easter Rising.
