Picture of the week: Garda facing up to the dissidents
A member of the Garda exposes the face of a masked member of a republican colour party on the centenary of the Easter Rising in Dublin on Monday.
The officer's action highlighted the Irish government's zero-tolerance policy towards any dissident activity in the Republic for the Rising Celebrations.
On Easter Sunday 1916, Irish republicans launched an armed rebellion in Dublin in an attempt to end British rule in Ireland. The rebellion lasted for six days and chiefly involved members of the Irish Republican Brotherhood, the Irish Volunteers and the Irish Citizens Army, before it was quashed by the British.
Almost 500 people died; the bullet-holes can still be seen on landmark buildings in Dublin's city centre today.
This week there were commemorations all over Ireland to mark the centenary of the Rising, attended by hundreds of thousands of people. Easter Sunday itself saw a huge military parade, with the 1916 Proclamation being read out in front of the GPO on Dublin's O'Connell Street.
The building served as the republican movement's headquarters during the Rising.
After the reading of the proclamation, Irish President Michael D Higgins laid a wreath at the GPO and military planes performed a fly-past over Grafton Street.
Earlier that day, Mr Higgins also laid a wreath at Kilmainham Gaol, where the republican leaders were executed for their role in the Rising.
There have also been a number of celebrations in Northern Ireland to mark the centenary, though Mr Higgins has withdrawn from a civic dinner due to be held at Belfast's City Hall next Friday, citing a lack of cross-party support on the council for his decision. (The DUP has confirmed it will not be attending the event.)
Only one unionist councillor, Jeff Dudgeon of the Ulster Unionist Party, has confirmed attendance.
