Presient Higgins and Taoiseach Enda Kenny led tributes
A ceremony to mark the 101st anniversary of the 1916 Easter Rising has taken place in Dublin.
The event outside the GPO on O'Connell Street was led by President Michael D Higgins, Taoiseach, Enda Kenny and Minister with responsibility for Defence Paul Kehoe.
Defence Forces personnel - including a brass band, a pipe band and representatives of the Army, the Air Corps and the Naval Service - also took part.
At noon the Tricolour was lowered and the 1916 Proclamation was read by Captain Michael Barry from the Defence Forces.

President Higgins then laid a wreath to commemorate those who died in 1916, while a minute silence was held.
Members of the public also attended and large video screens were put up on either side of the GPO.
An Air Corps fly past concluded the ceremony just before 12.30pm.
A seperate event has taken place at Glasnevin Cemetery, with wreath laying ceremonies at the Sigerson Monument and the graves of Edward Hollywood (the man who delivered the first Tricolour flag to Ireland from France) and Peadar Kearney (the composer of Ireland's national anthem).
Arts Minister Heather Humphreys was joined by the Deputy Head of Mission at British Embassy, Neil Holland, members of the Irish Defence forces and chairman of Glasnevin Trust, John Green.
The centre piece of the event at Glasnevin was the raising of the Tricolour at 9.40am by members of the Irish Defence Forces and the playing of the national anthem by a lone piper in the main courtyard.
