Belfast: Amid threats from terror groups, Northern Ireland’s police forces were put on high alert on Saturday. In an unusual move, the province's police force warned the public to be extra vigilant "due to the severe threat level posed by terrorists".

The Police Service of Northern Ireland (PSNI) said it believed dissident terror groups were "intent on trying to murder officers in the coming days".

The warning comes after rookie Catholic police officer Ronan Kerr was killed in a car bomb attack on April 2 and the discovery of a massive car bomb left in an underpass beneath
the main road linking Belfast and Dublin on April 7.

Authorities fear dissident republicans opposed to the peace process are increasing attacks ahead of May 5 elections in the province and a visit by Britain's Queen Elizabeth II to the neighbouring Republic of Ireland from May 17 to May 20.

"Dissident terrorist groups are continuing to identify officers and target them with the single objective of killing them. And, in so doing, their reckless actions will also put the lives of our wider communities at risk," a PSNI spokesman said.

"The public will see an increased visible police presence over the coming days and weeks and we ask for their patience with their officers if they are inconvenienced due to police activity.

"We are taking these steps to keep communities and their officers safe. We would not do this if it was not absolutely necessary to protect life."

The public alert, issued on Good Friday, comes 13 years after the Good Friday agreement, which largely ended three decades of sectarian bloodshed in Northern Ireland and put the province on the path to peace between Protestants and Catholics.

It also comes as thousands of mainstream Catholic republicans supporting the peace process prepared to hold dozens of commemoration parades to mark the 1916 Easter Rising
against British rule.

Three men were arrested on Friday when police stopped a car in Keady, a town close to the Irish border.

The PSNI described the arrests as "significant" and it is understood a number of undisclosed items were taken away for examination.

The men were detained as part of a security operation which also involved police from the Republic.
